We're not actually sure if Beth Ditto is biphobic, or if she just hasn't quite got the capacity to understand what "bisexuality" means. But she's had a pop at Angelina Jolie:
Eh? What on earth does that mean, Beth?
Uh... yes. That's why she's always said she's bisexual, Beth. You have to hope that she's not one of what we'd hoped were an almost-extinct type of homosexual, the sort who believes that there's no such thing as bisexuality and believe that all bisexuals are either gay people who are too scared to "properly" come out or straight people who are trying to make themselves more interesting.
If Beth Ditto were actually as feminist and sassy as she's supposed to be, she wouldn't come out with such monosexist cant.
