By Joseph Enders, Church Militant - When asked by commenter Mark Levin about the group over the weekend, Attorney General William Barr outlined who these groups are: "Well, I think they would be generally for bringing down any administration. They are a revolutionary group that is interested in some form of socialism/communism — they're essentially Bolsheviks."... Bolsheviks were revolutionaries that overthrew Tsar Nicholas II of Russia in one of the bloodiest civil wars in human history — with around 12 million casualties.
