Communists were murderous and they are/were not necessarily Serbs. There were many if not more Croats, Bosnians, Albanian Commies...no single ethnicity is responsible for the Marxist horrors unleashed on innocents over the years whether in the Balkans or in Asia.

If we have a few more muslim attacks on this country, Mecca will disappear in an atomic cloud.
