There is absolutely no reason why a homosexual "lifestyle" should be inherently more hazardous than a heterosexual "lifestyle". HIV is a predominantly heterosexual problem in much of Africa, which highlights the true issue, that sexually transmitted diseases are to do with poor education, ignorance often promoted by religion and the unavailability of condoms. You are using statistics to shore up your moral crusade, when the statistics actually reveal a lot more about what a bunch of numpties we are when it comes to sex education and how easy it is for religion and moralising to get in the way. It's the same with the horrid abortion rates. Moralising perpetuates these problems. Leave your morals at the door, stop being so bloody triumphalist about statistics that actually show something you're not talking about, and think about practical measures just for once.
