Answer me this then: How did life under Stalin’s Communism differ from life under Hitler’s fascism? Both centralise power in the Party, leaving no freedom for the individual. Both take the view that every citizen must serve the Leader and the Party, or die. Read George Orwell’s 1984 for an excellent critique of all that is wrong with the Socialist Revolutionary. Big Brother could represent Stalin or Hitler: they are equivalent.
This has nothing to do with Holocaust Denial, at all. It is just a statement that Big Government is the enemy of the individual, regardless of whether the Big Government has Fascist or Leftist rhetoric: rhetoric is just words: actions are what matter. The 20th Century proved that Socialist political and economic dogma were unworkable drivel, and caused the deaths of Millions.
