I can't think of anything more blissfully perverse than running around saying "Being a Nazi might be bad but at least it's not as bad as being a Commie!"
The fact remains that Communist regimes have killed more people than the Nazis did. Therefore, being a Communist is
worse than being a Nazi. If people will not admit that the Communists were worse than the Nazis than Communism will still be an acceptable ideology. Both are evil. To ignore the fact that the Communists killed more people than the Nazis did is to lessen their crimes against humanity. The only way to stop any totalitarian regime is to realize that they are all evil!
