Yes. And KKE members are either complete morons or scum, as far as I am concerned. But they are still people who happen to be victims of a felony, a violent attack. It is rather odd, to cheer actual, realized thugs on, just because their victims' ideology makes them even worse thugs, potentially.
The Nazis and the Commies are potentially thugs because they are collectivists - they think in terms of belonging to one or another group ("races", "classes", etc) and don't care what happens to real, individual people. Well, not being Nazis or Commies, we do, right?
