Sexuality
The big problem lies in the common perception that human sexuality is binary. You're gay or you're straight. (And bisexuals are just more gays anyway.)

If people started considering sexuality as more of a gradient, flowing from complete heterosexuality on the one side to complete homosexuality on the other, with neither end really being achievable, they would get a more accurate idea of where they themselves place.

Yeah, so you may like looking at other blokes' cocks when you're at the urinals, but that doesn't mean you necessarily also want to suck it -- and have to beat up some random fellow wearing a pink shirt because you feel dirty about it.

I also don't understand why it is such a big deal what you choose to poke yourself into (or have poked into yourself) as long as you stick to your own species.
