Obliviously, you are so ignorant of any study or knowledge of the Russian Revolution whereas the leaders of said Revolution could not get the people to get down with the class struggle but instead divided the population on race, and ethnic lines.  Or Communist Red China where they made the doctors dishwashers and the dishwashers doctors so that all could be equal. Was your family there?  How else can such vapid ignorance be explained? You are not fit to lick Palins boots.
