@Alex
I was worried there for a second. I thought someone had made a logical argument why my comment was rubbish. Turns out you were just saying "Oh don't pick on the Nazis, you big meanie ", which is possible the most ludicrous thing anyone can say. Nazism has racial hatred at its very core, as formed _by_ Hitler and by those who surrounded him (perhaps more so). You _cannot_ sympathise with Nazis without being a sick, twisted individual, who is not welcome in society.
Of course Islamic extremism isn't the same as Nazism, I was just using it to illustrate a point on freedom of speech. You _can_ be a Muslim without being an extremist (unlike the Nazis). Indeed, the majority of Muslims want the same as everyone else, to have a family, have a home, have a steady income and, hopefully, not to get blown up.
Also, at no point did I mention communism. I do distinguish between between communism and fascism. The former does not _have_ to lead to racial purges, but tends to as a result of the paranoid totalitarian government that seeks to run it.
