bisexualism 

negativity towards bisexuals. often, the negation of the very existance of bisexual people - instead believing that bisexuals are undecided in their sexual orientation, and are actually "straight" or "gay".

this is a commonly heard example of bisexualism:

"he says he's bi, but we know he really just goes for dick."
