My parents think I'm gay

It all started last week when I had some friends over. They decided it would be funny to leave gay porn saved on to my computer. My parents were the first to find it. We had a long, awkward conversation at the dinner table and they didn't believe me when I told them it was my friends who did it. They started to check my computer every once in a while, and they soon started checking my emails. Someone had sent me a fake letter saying something about thanks for subscribing to our fag porn site. My parents had a talk with me about this also. Now they think I am gay and they won't allow me to bring any of my male friends to my house unsupervised. This sucks. What should I do to prove that I'm not gay?

BTW my parents are hardcore catholics. They hate gays.

Who the fuck cares what your fucking parents think? They're closedminded faggots. If you want to be gay, be gay. If they don't like that, they should have added to Cho's high score.

If your parents hate faggots, they should fucking die. It's just as simple as that.
