She signed an Asian-American fan's copy of her book with a buck-toothed caricature, the words "ching chong", and a white hooded figure that is vaguely KKK looking. That may be "part of her act", but if her act is "I pretend to be racist to make fun of racists", it's still not right to be racist to your fans.

I think it's also really problematic for white people to spout racist shit and then say "oh, I didn't mean it, I'm just being ironic", period, even if it is part of an act.
