A main reason for AIDS being prevalent within the gay community is that it\'s known emergence is traced back to a very promiscuous gay man. So you had mostly gay men with AIDS, and then there\'s drugs, and the few who\'re bi, so that leads to heterosexuals.
As for the threat of contracting AIDS from a gay man or woman \'turned\' straight, I don\'t quite see your point, unless you have a problem with condoms.
As for marriage, I don\'t see a point in it, other than for it\'s legal and economic benefits, and it should be for anyone who wants it. I don\'t have a religious reason for marriage, being an atheist, and I really don\'t feel like I need a legally binding contract to tell someone that I love them. And then there\'s always the problems of divorce (unless there\'s a pre-nup) and don\'t get me started on annulment.
And as for homosexuality itself, good for them, means that many more women left for me. Most of my friends are gay or bi, and the only real difference I see is that the sex jokes and talk about sex switch genders mostly.
Also, when it comes to statistics, I hate them all, because you can say anything with a statistic; give me raw data any day.
And just because you\'re gay doesn\'t mean you can\'t, or won\'t, have children; I\'m living proof of that.
