To be fair though, the Nazis really only got their apparatus of mass murder going during the war - so they managed to kill about 20m in around six years (probably less, actually)- extrapolate that out to the 30 years Stalin was in charge and their figures would be significantly higher than Stalin's (and would've been if they'd been in power for 30 yrs). But it doesn't matter who killed the most people. The fact is we fought a war that saw millions upon million die to eradicate Nazism (Germany still has legislation preventing displays of Nazi symbols and holocaust denial etc) so when we see it rising again (in the supposed home of the free, of all places) then yes, we must oppose it with all our might.

As AJ rightfully pointed out - prior to 1930, the Nazi party in Germany was a joke. Fifteen years later, the entire world was in ruins, due to them. I for one have no urge to go through what my parents and grandparents did. Nazism needs to be opposed whenever it raises its evil head!...
