You hate people because you don't know them,
You don't know them because you hate them.
— Gil Grissom, C.S.I.Its just an irrational fear of what they don't understand.
I think people really shouldn't think differently of people just because they like boys instead of girls, or girls instead of boys. It really doesn't matter to me at all.
I'm asexual, so I pretty much don't have any.
Basically though, people have a visceral reaction to things that are unfamiliar to them, and to that extent it is natural. I was very adverse to any joint activity involving humans, but reaching beyond that I don't have opinions on the matter because I'm not really involved. I've grown up since I was in highschool, and and can appreciate romance in themes and such as that, and I don't see how either way is different beyond the breedability of each matchings. So, I'm not terribly surprised when heteros are disgusted and appalled by same sex romantic interaction, because it's different to them, and will always be different. That's why this irrational fear has gone back throughout history. It's really just a silly knee-jerk reaction that they can get over if they try. Some people have actually evolved to not even noticing the difference, and I find that beautiful.
But in summation, I find that I agree with the gay agenda: Wake up, eat breakfast, find spiffy shoes. :3
