Hair colour and sex isn't a whole different story, really. I'm sure you have a certain hair colour you prefer, right? There's this whole stigma with bisexuals that we are promiscuous and that a partner of one gender would never satisfy us, which is complete bull****. Gender is just another factor of a person's being, the same as hair colour, eye colour, height, fashion sense, etc. Bisexuals simply realise gender as a more fluid factor in their tastes.
And no, I don't have a gender I "prefer". I like both for varying reasons which cannot be defined with a simple "Which do you prefer" question.
Sorry, I'm getting kind of carried away. I wasn't arguing against you, I was simply emphasising my point which was addressed in your previous post. I realise that bisexuality is a foreign concept and hard for monosexuals to understand, but that doesn't mean it shouldn't be accepted. The same way that homosexuality shouldn't be accepted because heterosexuals don't understand it.
