well that seems nearly reasonable.
I am not sure i entirely agree with 1. while i dislike the laws, adn think deniers should be free to be ridiculous and ridiculed in public, at the same time most of the laws are about incitement to violence, not actually denial of the holocaust.
you can see why germany has laws against denying nazi war crimes - they learned their lesson the hard way.
so while I dislike the laws, I cannot see why anyone would cliam their existence is a barrier to understanding that it did actually happen. to me that is just posturing. the truth does not fear investigation, and you may investigate. and find the truth is that they killed millions.
2) well Treblinka is being investigated, and I await the results. It is a mostly english and polish team.
but I am not sure that (and a dig on Auschwitz) would prove much. yes they found the huge mass graves, which proves a good deal, but would that be enough?
would we be able to find the evidence at Auschwitz, given the ways they disposed of the ash, according to the camp commandant, and all other witnesses, independently?
If one could prove that about 2 million died in those two places, (and another half million to three quarters in the other major death camps) would that be enough?
That and the 1.4 million from the Einsatzgruppen (as if they are not in themselves enough to debunk most deniers on this board)? so that would give about 4.1 million.
the rest - well 250k in your country... and hundreds of thousands in every nook and cranny of europe.
so a total of 5.1 to 5.7 million isn't hard to get to.
but really, is there not enough proof of those things already? deniers nit pcik with stupid things like the wooden doors (not original, not on the gas chamber, not relevant) but the rest of the evidence, which they have not looked at, is pretty strong...
and as for 3 - well those are good ideas, but again, they are not sufficient to doubt it happened.
