The legitimate concerns of bisexuals are regularly lumped in with what you're talking about. Which really isn't a common thing. It probably does happen, but not nearly as much as. You know. Bisexuals actually being discriminated against by both heterosexuals and gays and lesbians. And I'm sorry, but even if I disagree with any "more oppressed" arguments, quite frankly, I cannot blame anyone for being disgruntled when they get shit from both homophobic straights and the rest of the queer minority umbrella. And seriously, on what planet is it not a problem that myself and other girls like me have both had straight peers balk at them for being sexually attracted to women, and have had lesbians flat out tell them that they wouldn't ever consider dating them because they're afraid they'd just leave them for a man?

Those were not examples of anyone actually saying that. Those were examples of people claiming they've seen it, and one idiot using the word "heterophobia".
