I'm more concerned of the fact that you can't question it AT ALL. It's 'anti-Semitic' or 'racist' to do so. You're stopped from asking questions or pointing anything out. You're immediately classed as a heretic and insulted. That alone really gets my interest and start questioning things.
I've been to Auschwitz. September 2010. Things happened there. People died. How many died I don't know. Could be 1000s, could be millions.
But classing me as 'anti-Semitic' because I or others dare talking about it ... go fuck yourself with a retractable baton.
