I'm not.
And I used to think gay people were all weird, and as such avoided them.
then, one night, while drinking with some ladies in their dorm, and then backing some brownies because, I met her gay floor-mates. And they were pretty cool guys. Didn't flaunt it much, just like "and this is my boyfriend" didn't come onto me, and we all had friendly chat.
This, combined with other social events at that time, I learned that sure, people may believe/do odd things, but THEY'RE STILL PEOPLE, and when they're not hurting other people, it's all good. So yeah, if you're attracted to the same sex, good for you! I personally am not, but that doesn't mean you're wrong, so long as you also accept me.
the thing is, its a fear of the unknown, which can only be broken by facing it, and its much easier just to join with other people whom hate instead.
