Interesting - I hadn't known the history behind the term, I thought it was a neologism. I do prefer the term identity politics myself, but the tendency of right wing groups to call everyone they dislike communists doesn't appear to me any more ridiculous than the frequency with which they are called Nazis. There seems to be an effort in that camp to shift the Overton window to exclude communism with the same prejudice currently reserved for Nazism, and from that perspective 'baiting' the opposition into being too loose with either term is probably an effective strategy.
