Everyone who claims homosexuality is a sin must necessarily be bisexual. Here is why.
According to the traditional definitions of sin, sin must always involve a
choice. Thus, the claim that attraction to the same sex is sinful implies that attraction to the same sex is a choice. But no one chooses who they are sexually attracted to. Nevertheless, people who are bisexual can choose to
ignore one aspect of their sexuality, so that they can have the
illusion of choice. This is why we see so many bisexual people claim to have "found Jesus," and "repent" of their homosexuality, and make the "choice" to be heterosexual. In reality, they are simply choosing to ignore the homosexual aspect of their sexuality and choose to only focus on the heterosexual aspect.
For people who are either 100% heterosexual or 100% homosexual, sexual orientation is not a choice. For instance, I could not choose to be attracted to men, even if I wanted to be. In the same way, a homosexual person could not choose to be attracted to the other gender if they wanted to be. A person who is 100% heterosexual or 100% homosexual would understand this, which begs the question, why do so many Christians, especially pastors, claim that homosexuality is a choice? I think that the only logical answer is that bisexuality is fairly commonplace in the population, and likely even more common among Christian pastors.
So, since our conclusion implies bisexuality is likely much more common in Christian pastors than in the rest of the population, we should encourage these pastors to celebrate their bisexuality, rather than trying to mask it in
homophobic preaching. A study has already confirmed that homophobic men who claim to be heterosexual have measurable responses of arousal to gay porn, while non-homophobic heterosexual men do not. See this study, which verifies my ideas.
