I was taught to think that way too.
But I learned, over the years, that it isn't that simple.
Like I said, I have many friends who are gay and lesbian. No one would CHOOSE to go through the hell they lived through. Many of them are shunned by their families. They have very hard, very tragic lives.
But you don't have to understand them or even agree with me about this. What I object to, is people who actively support violence against others because they are gay.
