@aaaaa As I said, my position is clear, you just don’t like it.
You’re right about “sexual preference”, choice of words wasn’t the best, I should’ve written  “You are sexually attracted to women”. Homosexuality is a natural phenomenon, not a choice (preference), it’s a disorder common in all of animal kingdom. There are examples of all kinds of animals displaying abnormal sexual behavior. 
Well, first time I’ve heard of bug-chasing it was a hetero-sexual orgy. HIV was first transmitted to people from monkeys, to hunters from their pray, by blood. That happened in early 20th century. Misleading stance that HIV is a strictly homosexual thing is what helped spread it the most in the 80s when it was discovered and later on.
