I'm guessing this excerpt begins to speak to the problem:
QuoteProtesters began to be a problem for Bitch after she crossed picket lines to play at the Michigan Women's Music Festival despite a boycott that was in effect at the time and voiced her support for Michigan's policy of excluding trans women.
There is further elaboration suggesting/establishing that Bitch sees trans people as their birth sex rather than as their true gender. This in of itself represents a problem, but it may potentially be one that she could be talked away from. However, I suspect that her breaking a related boycott *and* actively voicing support for the policy did her in, and as per her idiom has shown no interest in apologizing or even acknowledging legitimacy in the complaints lodged against her, all while tossing in a pinch of racism.
