Aside from the illegality of some of your examples, faithful monogamy still would work to prevent the spread of AIDS.
This is a good example of evolution at work.
Considering homosexuals can't produce children and are an intrinsically disordered genetic dead end I can only assume you speak of the evolution of various 'bugs' that homosexuals through depraved activities allow to take a survivable foothold in society.
I don't think it is so much evolution of the 'bugs' than I think it is simply devolution of the disordered hosts (risky behavior and self gratifying short sighted stupidity) that accentuates and accelerates rare 'bug' occurrences by providing filthy environments (e.g. colon penetration) that culture incubate and easily transmit that which should be rare; e.g. all the diseases etcetera that rear their ugly heads during carnage of war or natural disaster...
The rare 'bug' colonies require petrie dishes and homosexuals sure are providing them...The 'experiment' is decimating homosexuals quicker than heterosexuals -survival of the fittest?
