Yes they are people who prey on young boys, but the thing is that not every homosexual preys on young boys and girls. My friends want what most American want -- lower taxes, less government and free trade. They don't want to out acting like fools at Gay Pride Parades - they are disgusted when the DBM show guys in THONGS or dressed as girls and women who look like they could play linebacker for the PATS.
One of my friend owns a marina that is one of the biggest in Maine. If you look at him you wouldn't think he is a millionaire (he wears deck shoes no socks shorts in the summer Khakis in the winter, polo shirts), but he is. He wants to drill for oil off the coast of Maine. He has a son that he got 'biologically' (he was married, but his ex left him - she took off with her boss) and now he does have a partner. The son, is a friend of RWT (and no, he isn't gay - he wants my daughter in 9 years), but he is a great kid. He loves his dad and his 'uncle', but he supports the gay boys too. "God made us to be loved, and he decides on who we love," his his favorite saying.
I hear what you are saying. On a personal level, I have been friends with, and even rented from, people who were Lesbians. I take people on a case by case basis in my personal life. On the other hand, I once found myself on an elevator alone with Jim McGreevey, and refused to acknowledge his presence. But when we speak of it as a public policy matter, in broad brush strokes, I am concerned that the law preserves my right to take people on a case by case basis and does not require me to associate with those I do not wish to. To use your example, I would always want to stay well away from the flamboyant gay pride goers.
