It actually makes perfect sense. Fascists and Communists have been bitter enemies since Day 1. Just look at the Spanish Civil War, and WWII, which was mostly about Fascism (Hitler and Mussolini) vs. Communism (Stalin), until the Japanese went and bombed Pearl Harbor.
So this person is fearfully McCarthyistic 35 years after the CCCP SPLINTERED ??
All those people, and not a single grey cell between them.
