Keep in mind..Marxism is actually a religion...and a fanatic one at that. Just as the most radical Islamists will do some terrible, ugly deeds, so the
fanatical Marxists can behave. (e.g. the killing fields)
Communists can be just as brutal as any other hate based religion.. Consider the Chinese communists, during their "cultural revolution",
spanning the years from 1966 to 1976. I can recall the startling news reports coming out of China, and they were not pretty...
Don't think for a moment, that some crazy leftists here, could not do that to Christians or other non compliers, should they gain full power..
