Why Are Guys More phobic Than Girls?

I'm pretty sure I kinda know why but it doesnt hurt to ask. I'm a straight girl and I've always had no problem with gays. the girls in my school don't really seem to either. But all the gay guys have girl friends, never any guy friends. If you ask me, I don't think most girls are all that evovled on the gay issue. There are many that I'm sure wouldnt be as cool with s, and they say "that's so gay" and "f@g" as much the boys. What do you gus tink?
