3) Increase of homosexuality. Cultural endorsement of, and incentives for, homosexual behavior will likely lead to a higher incidence of homosexuality in the population, affecting young people at higher rates. This means that more people will develop a higher risk for the problems discussed in 2 above. For documentation of this point, see The Bible and Homosexual Practice, 395-429; and now with updates, “Why the Disagreement…?” pp. 30-32, 120-25 here.
First of all, the language Gagnon uses here is a bit misleading. We are a long long way from cultural “endorsement” of homosexuality. There really are no “incentives” to be verbally abused, socially excluded, threatened with and subjected to violence, or denied equality under law. The operating category here is not whether our culture can “endorse” homosexuals, but whether we can get away from bigotry towards them. By using the language of endorsement and incentives, Gagnon, invokes a false dichotomy between rejection and preferential treatment. It is ridiculous to suggest that homosexuals receive or desire preferential treatment. It is the case that they are subject to discrimination.
Beyond the twisted language however, this simply isn’t an argument that matters. If people stop attacking homosexuals will more people acknowledge their homosexuality? Yes, and that’s a good thing. What could possibly be good about people continuing to suffer in silence? What could possibly be good about emotional repression, self-recrimination, false identities and a never-ending string of relationships predicated on lies? Even if one believed that homosexuality was sinful there is no benefit to it remaining in the dark, hidden because of social pressure. There is an urgent need for our culture to accept homosexuality so that the trauma that is being done can begin to be healed.
In addition, it just seems like unwarranted hysteria to presume that cultural acceptance of homosexuality will lead to some kind of massive surge. The contention of homosexuals, with growing scientific support, is that their orientation is biological. There is no reason to presume that it is “contagious” or that otherwise heterosexual individuals will somehow be converted, which is what Gagnon seems to imply by saying young people will be “affected”. The “increase”, if it happens, will only be the long-overdue revelation of those who society has been suppressing.
