Like I argued in 'The Mass Psychology of Anti-Fascism', you should never apologize to Zionists and their agents in the left. Longtime activist Greta Berlin accidentally tweeted a link to a video which was sort of halfway between a reasonable critique of Zionist-Nazi collaboration and an exaggeration of it. Her 'Free Gaza' movement then came under attack by the usual suspects, and now they are adding to the list of verboten activists. What Greta should have done, is post a real Holocaust denial movie, and raised her middle finger.
