That's the nuance to her comments. Could she have put it better, probably, is she anti-semitic and was she making the point to incite anti-semitic sentiment, no.
I never said everyone criticising her was white, but the vast majority of the offended people in the meeting she made the latest comments at seemed to be from the video, and the vast majority of people on twitter calling for her to be sacked, and from a quick trawl I think the same applies to most of the media commentators.
John Mann is a particularly vocal example;
That's a white non Jewish man accusing a black half Jewish woman of inciting an anti-semitic racist backlash and holocaust denial.
Here's something else she said at the recent meeting prior to the holocaust comments.
Pretty bad IMO that the next thing that happens is that one of the highest profile BME activist to attempt to address the issue is then hounded out of the party and Momentum. That seems a very odd form of anti-racist action.
