I like some of his music, but I can admit that a lot of the lyrics are sexist and offensive. But just because it's offensive doesn't mean I can't enjoy it.

You can recognize the shitty things about something and yet still be a fan.

So yeah, if you had said you were a fan and recognized that he can be pretty offensive and sexist yet you still love his music, that would have been cool. But the fact that you can't see it at all? Yeah, you might be that "bad feminist" you speak of.
