In my experience I think people are generally a lot more accepting these days of homoloveuality and stuff, as you can see from the gay marriage things being approved in some states of the USA at the moment. But I do think that a lot of people dislike the gay stereotypical behaviour and personality more than their loveual preference. Personally (and I know its probably wrong to say and all that) I can't stand those flamboyant gay types who dress in vibrant colours, talk with a stupid lisp and just act outrageously gay. Its no problem if you act like a normal person but happen to like dudes though. I recently found out one of my best friends from my last school was homophobic too but I haven't bothered trying to change his mind or anything, it's pretty futile.
There is merit in this, and I can agree. There are quite a few gay people in my school and some are the "Heeeeeeeeeeeyyyyyyyyyyyyyyyyy!!!!!!!!!!!!!!" type while others I'm like "Oh wow, I would never have guessed". I am not sure if they are like this because they are gay (most likely not), or just because they just happen to seek attention. I know one of my teachers confronted a friend of mine for being too gay (i.e writing an essay about his studmuffin for English, constantly touching people, etc.) Of course, we can't generalize the whole group, but it seems a lot of them dress loudly. I do find their company interesting but, like everything, it gets old. It's like "I get it, your gay." Still, they are nice people no doubt about that.
Perhaps its just they are more confident and more comfortable with themselves, and perhaps, we could all take a lesson from them.
*NOTE* I am only basing this off where I love, which is a rather gay state.
