A person who seeks a relationship with the same gender. Many people are disgusted by it for the following reasons, all of which are incredibly stupid:
It's disgusting because it's unnatural!-
So? Breast implants aren't natural, but I don't see you complaining about them.
It goes against God!-
Not everyone reads the Bible. Stop shoving your religion up my ass, plzkthnx.
Watching two people of the same gender make-out is gross!-
Eyelids, closing them tends to block your vision so you can't see. Besides, watching anyone have a tongue fight, homosexual or not, is really kinda gross.
Those are just a few amongst many other idiotic reasons, I'm sure.
