Communism doesn't have inequality, brutality, racism, authoritarianism and unquestionable devotion to leaders built into its founding principles. Fascism does. Communist states have obviously frequently succumbed to these dispicable realities, through corrupt leaders and failed policies, granted. But the ideals on which the theory is based are sound.
Its a cop out to say it, but it just seems to me communism just hasn't been done properly yet.
I will add, I'm no expert in either political thought or history. My arguments could probably easily be torn apart by anyone with a bit more knowledge. I never claim to be a political anorak or theory expert but the basics aren't that hard to understand, and I believe that the principles of commie theory are sound and fair, whilst fascism is dangerous and hateful by nature and the reality has shown this to be undoubtedly true. Fascism has "worked" and it was shit. Communism has never been implemented properly.
