Some stereotypes there.
A Christian in general, when they hear the world Satanist is going to assume this:

Not this:
A Satanist on why everything you think you know about his religion is wrong
(Assuming they're telling the truth, of course)
On the other hand, there are plenty of open-minded individuals of all faiths. And for the record, most churches nowadays do accept gay members. There is a difference between accepting members, and accepting priests. There is also a difference between accepting priests who do it in their private life, and being told they MUST hire openly gay priests or perform weddings (this basically tore the Episcopal church apart, since it was like a government mandate to perform actions or be fired for "bigotry"). The guy in Colorado? Yeah, these little ****s came from Massachusetts, could have held the wedding there, instead decided to travel to Colorado just to make a political statement or something. They ruined the guy. He was fighting for years, until finally Supreme Court handed out a verdict (we don't have right to discriminate, but these guys clearly overstepped their bounds since he was willing to bake them a cake just not participate in the wedding, and they went hysterical and sued him for that).
Here's the official stance of the Catholic Church.
The Catechism of the Catholic Church, a text which contains dogmas and teachings of the Church, names “homosexual acts” as “intrinsically immoral and contrary to the natural law,” and names “homosexual tendencies” as “objectively disordered.” While the Catholic Church does not consider “homosexual orientation” sinful in and of itself, it does have a very negative attitude toward it. The 1986 Letter states, “Although the particular inclination of the homosexual person is not a sin, it is a more or less strong tendency ordered toward an intrinsic moral evil; and thus the inclination itself must be seen as an objective disorder.”
The fact that Catholicism does not consider the “inclination” sinful is very different from more fundamentalist Christian churches. It is one of the reasons that the Catholic Church has not officially approved of reparative therapy. The Catechism further states that “Homosexual persons are called to chastity.” However, the doctrine also specifies that, “Such persons must be accepted with respect and sensitivity. Every sign of unjust discrimination in their regard should be avoided.”
The actual experience of LGBTQ parishioners can vary widely across dioceses and parishes. Many Catholic communities reach out to LGBTQ members to offer as full of a welcome as possible within the limits of a Church policy that does not approve of same-sex relationships, even committed ones. Other parishes have denied membership to LGBTQ individuals and families. There have also been recent instances of LGBTQ employees in the United States being dismissed from Catholic schools and parishes following the celebration of a same-sex couple’s marriage.
TL;DR version, yes it's probably not good for you, no you're not any more a sinner than any other person. You're encouraged to be abstinent, but they shouldn't discriminate. Whether or not they do... depends on the priest.
Which is kinda the topic really. Those same words, the priests interpreted several different ways based on what they wanted. Likewise, I'm pretty sure I will never convince you from that quote that Catholics are super-accepting.
