That could be a good poll. It is strange but when it comes down to oppression communism is much worse than fascism. Check out the series on BBC 2 at 9 tonight about life under communism. Last week it was East Germany. Tonight Czechslovakia
Without wanting to derail the thread, you could argue that they were not true Communist states, rather Stalinist which was a form of Fasciscm anyway. Look to Cuba for the nearest realisation of the Marxist ideal or maybe Chavez's Venuzula (although it's early days). Highly popular genuinely egalitarian systems of self government.
