One Should Never Question the Holocaust

So watching this video is clearly illegal and will give you impure thoughts:

If you do watch the video, it's clear that:
1) the gas chamber layout is non-sensical
2) the SonderKommando story is ridiculous and illogical
3) the crematoria was completely inadequate for mass disposal of bodies

These are simple facts, and have nothing to do with anti-Semitism. Neither does this absolve the Germans for their clearly atrocious treatment of Jews. But there are clearly major problems with the official Holocaust story. At the same time, the elites (and definitely not just Jews) hysterically try to prevent questions being asked about it. It's completely insane that it's illegal in some countries to even publicly raise questions about the Holocaust.
