Saluting Nazis is not okay! But get caught carrying pictures of Chairman Mao (death toll around 70 million), have a poster of mass-murderer Che Guevara on your wall, wear a Che Guevara T-shirt from Hallensteins or go sipping revolutionary coffee in the Havana cafe&bar (paying homage as you do to the murderous Cuban revolution) and you fit right into today's culture.

Che vociferously opposed freedoms of religion, speech, press, assembly, protest, or any other rights not completely consistent with his North Korean-style communism. How many rock music-loving teens sporting Guevara t-shirts today know their hero supported Cuba's 1960s' repression and murder of rock music fans? How many homosexual fans know he had gays jailed?

Why not head down and relax at the Lenin Bar in Auckland, which pays homage to the man who unleashed the Bolshevik state upon the world and the Cheka upon the Russian people, and you'll be surrounded by the very journalists writing all those outraged articles about students dressing up in Nazi fancy dress – and who'd be just as violently outraged if a Hitler Bar, a Himmler's Death's Head Bistro, or Goering's Gelatos bar were to set up next door. Surely something is wrong here?

Nazism is still rightly reviled, but the philosophy that killed 100 million people and at one time enslaved around 60 per cent of the globe is still given house room. How can that be?

Che Guevara was an international terrorist and mass murderer. During his vicious campaigns to impose communism throughout Latin America, he trained the Castro regime's firing squads that executed thousands of men, women and children.

If you want to track down modern history's biggest mass-murderers, your best two resources are Rummel's Power Kills website and the Black Book of Communism.

Read them and weep.
