Whether homosexuality causes HIV is surely immaterial.
Despite claims by some of those here, homosexuality is not a "chosen lifestyle" - it is a natural state mor many millions of people - it is not "curable" as has been claimed by the church (and be people here - again)
Given that it is natural for some people, H.I.V. is something to be regretted rather than used as a weapon to vilify homosexuals (as is happening here).
Whatever the truth about causes of HIV (still wrapped in mystery - even by the experts), the argument should be how to deal with it rather than to use it as a weapon against people whose sexual inclinations you disapprove of.
The most common sexually transmitted diseases are syphilis and Gonorrhea, both transmitted by heterosexual sex.
I have yet to hear anybody suggest that because of this, heterosexuality should cease, or be a cause of condemnation of a sexual practice.
Personally,I find the gleeful reveling in the claim that HIV is caused by homosexuality sickeningly medieval - almost as much as I find some Churchs claim' that it is "God's punishment for an unnatural act" - I suppose I'll have to put it down to the fact that I don't understand Christianity, I suppose!
