So accusing her of racism is race bating. Still seems odd to me, but I get lost on a lot of race issues.
Here's what I understood it to mean. When Ann says Halle Berry 'mau-maued' her way to the Oscar (oops, 'scuse me: 'Academy Award (TM)'), she means that Berry or someone, applied race-based pressure against whites to give the award to a 'black actress' even though (in Ann's opinion) the actress in question didn't really deserve it (unlike Denzel Washington, who did). As nearly as I can make sense of it, this Kane fellow is saying that Ann is 'all but' accusing Berry of terrorism, because the Mau Mau's intimidation techniques were not unlike the KKK's.
If that ain't what's going on, then your guess is as good as mine and maybe better. Kane isn't the clearest writer ever born.
Thanks, now I understand the accusation. I wonder if there's any basis to it. (Neither ann nor Kane were clear, I'm afraid.)
