FYI the original version of the poem about the holocaust starts with "First they came for the *communists* ". The reason you might not know this is that in an act of extreme irony and cynicism they took out that first line for the version they put on the US holocaust museum.

I try to avoid sectarianism on twitter but it's hard to suppress the frustration and contempt I feel towards the American anticommunist "left". If your politics are based on seeking validation from liberal middle-class friends & family, now's a good time to rethink priorities
