Which was worse: Fascism or Communism?

Zizek writes an uncharacteristic article: straightforward analysis. "In Germany, many CDs featuring old East German Revolutionary and Party songs, from ‘Stalin, Freund, Genosse’ to ‘Die Partei hat immer Recht’, are easy to find. You would have to look rather harder for a collection of Nazi songs. Even at this anecdotal level, the difference between the Nazi and Stalinist universes is clear, just as it is when we recall that in the Stalinist show trials, the accused had publicly to confess his crimes and give an account of how he came to commit them, whereas the Nazis would never have required a Jew to confess that he was involved in a Jewish plot against the German nation. The reason is clear. Stalinism conceived itself as part of the Enlightenment tradition, according to which, truth being accessible to any rational man, no matter how depraved, everyone must be regarded as responsible for his crimes. But for the Nazis the guilt of the Jews was a fact of their biological constitution: there was no need to prove they were guilty, since they were guilty by virtue of being Jews." His conclusion? "It is necessary to take sides and proclaim Fascism fundamentally ‘worse’ than Communism."
