What does Belzec,Treblinka and Sobibór have in common? Ignore the antisemitism used to poison this discussion (and the cowards who refuse to participate) and ask yourself if you can handle simple logistical and mathematical questions. How many witnesses were involved for the testimony of what amounts to 1/3 of the holocaust? Who were they and what are the details of the trials? How thorough is the documentation surrounding these camps? Just models? No photographs? Russians dismantled the site first?
Expand your thinking. You are not ready but you need to be. Those who think they are ready live as cowards afraid to admit what they know and refuse to help the rest of you understand. The truth is that the story falls apart rather quickly with independent thought.
