Posit: Homosexual behavior spreads terminal disease at epidemic rates among its practitioners, serves no useful purpose for society and causes excessive lost productivity both for those who contract the disease(s), those who must divert care from other conditions to care these diseased homosexuals and those who (through taxation) provide funding for the care and research for a cure/vaccine (in lieu of the same for diseases that are less avoidable and more widespread).
Posit: All human societies, in the interest of self preservation, limit, discourage, or prohibit by law voluntary activities which serve no useful purpose to society and cause excessive lost productivity both for those who contract the disease(s), those who must divert care from other conditions to care these diseased individuals and those who provide funding for the care and research for a cure/vaccine.
Conclusion: Society should, in the interest of self preservation and increased productivity, limit, discourage or attempt to prevent homosexual behavior through law.

What if they don't have anal intercourse? What if one guy squeezes his thighs together and the other guy rubs his c#ck between them. That's how the ancient greeks did it. I mean, when you think about it that way, it's not so different from a women squeezing her breasts together while her lover rubs his c#ck between them. Maybe the government could offer clinics on gay sex as part of a public health campaign for safer sex?
