It seems that many people are inordinately concerned with the sex lives of others. Gayness--if there is such a word--is determined long before we are born. See "We Are Our Brains" by DF Swaab.

Stating an opinion about gays or hereros or bis is one thing. Stating that opinion while ignoring or perverting the facts is another. But then we all know that opinions are like arseholes: everybody's got one.
