I'm Gay & Homophobic Watch
People are different, gays as well as straights. That someone is gay doesn't mean they are exempt from potential stupidity. The good news is that it works both ways. Your preconseptions about gay people are only true for a few, there are countless of others that don't fit the stereotype at all. Is it fair to guess you are still in school? If so I can almost promise you university is a lot better.
I'm inbetween college and uni
However, I have very close friends who are gay. The important thing to remember is that people are more than just gay, a lot more. I would suggest taking a dip into literature, Oscar Wilde, E.M Forster, or through history, Leonardo da Vinci, Micheangelo, Virginia Wolf, were all gay. There are also a lot of mordern gay literature out. The Line of Beauty for example, won the Booker Prize a few years ago.
