I was a member of labour and on the corbyn hardleft, so had every incentive to not believe what I reading. However it was maybe six months into knowing their name because of the scandal that I learned Jo Bird was Jewish. The firehose strategy works I'm afraid.
Talking of this largely manufactured crisis, I really don't believe Zack Polanski's claim that he believed what he read. Either (a) he wanted to believe it or (b) he didn't want to put himself in the firing line, to become another target of the non-stop screaming and denouncing.
