Here's an interesting article on some of the "research" that's been presented in this thread as well as results from some studies that paint a different picture
Timothy J. Dailey Ph.D. -- Homosexual Parenting: Placing children at risk
here's some excerpts:
"The presence of methodological defects--a mark of substandard research--would be cause for rejection of research conducted in virtually any other subject area. The overlooking of such deficiencies in research papers on homosexual failures can be attributed to the "politically correct" determination within those in the social science professions to "prove" that homosexual households are no different than traditional families. However, no amount of scholarly legerdemain contained in an accumulation of flawed studies can obscure the well-established and growing body of evidence showing that both mothers and fathers provide unique and irreplaceable contributions to the raising of children. Children raised in traditional families by a mother and father are happier, healthier, and more successful than children raised in non-traditional environments. David Cramer, whose review of twenty studies on homosexual parenting appeared in the
Journal of Counseling and Development, found the following:
The generalizability of the studies is limited. Few studies employed control groups and most had small samples. Almost all parents were Anglo-American, middle class, and well educated. Measures for assessing gender roles in young children tend to focus on social behavior and generally are not accurate psychological instruments. Therefore it is impossible to make large scale generalizations . . . that would be applicable to all children.1 "

Self-presentation Bias
A lack of random sampling and the absence of controls guaranteeing anonymity allow subjects to present a misleading picture to the researcher that conforms to the subject's attitudes or opinions and suppresses evidence that does not conform to the image he or she desires to present.
In their
National Lesbian Family Study N. Gartrell et al. found that eighteen of nineteen studies of homosexual parents used a research procedure that was contaminated by self-presentation bias. Gartrell mentions the methodological problems of one longitudinal study of lesbian families:
Some may have volunteered for this project because they were motivated to demonstrate that lesbians were capable of producing healthy, happy children. To the extent that these subjects might wish to present themselves and their families in the best possible light, the study findings may be shaped by self-justification and self-presentation bias.23"
"The evidence demonstrates incontrovertibly that the homosexual lifestyle is inconsistent with the proper raising of children. Homosexual relationships are characteristically unstable and are fundamentally incapable of providing children the security they need.
Homosexual Promiscuity: Studies indicate that the average male homosexual has hundreds of sex partners in his lifetime, a lifestyle that is difficult for even "committed" homosexuals to break free of and which is not conducive to a healthy and wholesome atmosphere for the raising of children.
A. P. Bell and M. S. Weinberg, in their classic study of male and female homosexuality, found that 43 percent of white male homosexuals had sex with five hundred or more partners, with 28 percent having 1,000 or more sex partners.29 "
"Promiscuity among Homosexual Couples
Even in those homosexual relationships in which the partners consider themselves to be in a committed relationship, the meaning of "committed" typically means something radically different than in heterosexual marriage.
In The Male Couple, authors David P. McWhirter and Andrew M. Mattison report that in a study of 156 males in homosexual relationships lasting from one to thirty-seven years: Only seven couples have a totally exclusive sexual relationship, and these men all have been together for less than five years. Stated another way, all couples with a relationship lasting more than five years have incorporated some provision for outside sexual activity in their relationships.33 Most understood sexual relations outside the relationship to be the norm, and viewed adopting monogamous standards as an act of oppression.
In Male and Female Homosexuality, M. Saghir and E. Robins found that the average male homosexual live-in relationship lasts between two and three years.34
In their Journal of Sex Research study of the sexual practices of older homosexual men, Paul Van de Ven et al. found that only 2.7 percent of older homosexuals had only one sexual partner in their lifetime.35"
"Substance Abuse among Lesbians
A study published in Nursing Research found that lesbians are three times more likely to abuse alcohol and to suffer from other compulsive behaviors: Like most problem drinkers, 32 (91 percent) of the participants had abused other drugs as well as alcohol, and many reported compulsive difficulties with food (34 percent), codependency (29 percent), sex (11 percent), and money (6 percent). Forty-six percent had been heavy drinkers with frequent drunkenness.49
Greater Risk for Suicide
A study of twins that examined the relationship between homosexuality and suicide, published in the Archives of General Psychiatry, found that homosexuals with same-sex partners were at greater risk for overall mental health problems, and were 6.5 times more likely than their twins to have attempted suicide. The higher rate was not attributable to mental health or substance abuse disorders.50
Another study published simultaneously in Archives of General Psychiatry followed 1007 individuals from birth. Those classified as gay, lesbian, or bisexual were significantly more likely to have had mental health problems. Significantly, in his comments in the same issue of the journal, D. Bailey cautioned against various speculative explanations of the results, such as the view that "widespread prejudice against homosexual people causes them to be unhappy or worse, mentally ill."51
"Sexual Identity Confusion
The claim that homosexual households do not "recruit" children into the homosexual lifestyle is refuted by the growing evidence that children raised in such households are more likely to engage in sexual experimentation and in homosexual behavior.
Studies indicate that 0.3 percent of adult females report having practiced homosexual behavior in the past year, 0.4 percent have practiced homosexual behavior in the last five years, and 3 percent have ever practiced homosexual behavior in their lifetime.54 A study in Developmental Psychology found that 12 percent of the children of lesbians became active lesbians themselves, a rate which is at least four times the base rate of lesbianism in the adult female population.55"
"Incest in Homosexual Parent Families
A study in Adolescence found: A disproportionate percentage--29 percent--of the adult children of homosexual parents had been specifically subjected to sexual molestation by that homosexual parent, compared to only 0.6 percent of adult children of heterosexual parents having reported sexual relations with their parent...Having a homosexual parent(s) appears to increase the risk of incest with a parent by a factor of about 50.60"
"Homosexual or lesbian households are no substitute for a family: Children also need both a mother and a father. Blankenhorn discusses the different but necessary roles that mothers and fathers play in children's lives: "If mothers are likely to devote special attention to their children's present physical and emotional needs, fathers are likely to devote special attention to their character traits necessary for the future, especially qualities such as independence, self-reliance, and the willingness to test limits and take risks."
Blankenhorn further explains:Compared to a mother's love, a father's love is frequently more expectant, more instrumental, and significantly less conditional. . . . For the child, from the beginning, the mother's love is an unquestioned source of comfort and the foundation of human attachment. But the father's love is almost a bit farther away, more distant and contingent. Compared to the mother's love, the father's must frequently be sought after, deserved, earned through achievement.69
Author and sociologist David Popenoe confirms that mothers and fathers fulfill different roles in their children's lives. In Life without Father Popenoe notes, "Through their play, as well as in their other child-rearing activities, fathers tend to stress competition, challenge, initiative, risk taking and independence. Mothers in their care-taking roles, in contrast, stress emotional security and personal safety."
Parents also discipline their children differently: "While mothers provide an important flexibility and sympathy in their discipline, fathers provide ultimate predictability and consistency. Both dimensions are critical for an efficient, balanced, and humane child-rearing regime."70
The complementary aspects of parenting that mothers and fathers contribute to the rearing of children are rooted in the innate differences of the two sexes, and can no more be arbitrarily substituted than can the very nature of male and female. Accusations of sexism and homophobia notwithstanding, along with attempts to deny the importance of both mothers and fathers in the rearing of children, the oldest family structure of all turns out to be the best."
