"There is not a single mass grave of holohoax victims."
The holocaust is usually understood to be the murder of millions of European Jews. Beside this there were many more people murdered and you wont be able to distinguish them looking into graves easily. Anyway, I guess you are rather referring to Nazi mass-murder in general, so here we go.
First of all concerning the graves: Of course they exist and most Holocaust-denier won´t deny them because it would make them look ridiculous. There is proof of graves, there are bones, there are ashes, there are pictures of open burnings, supported by remarks made by eye witnesses. And it´s not only ashes you will find: In 1967 e.g. people where exhumated in the concentration camp of Mauthausen (2nd picture refers to Mauthausen but was taken earlier as you can probably see)
So far so good. The question in my opinion is another: What means "proof" to the denier? And as far as I know the Holocaust-denial-scene "proof" means anything if it doesn´t support the own thesis, including rejecting arguments made in the past if flawed and still holding onto their opinion without any doubt.
I actually not only strongly believe that there were gravesites that have been mistakenly identified as "german" - I know. And its obvious how it happened: After war it was easy to be less accurate and to blame the Nazi regime for all without backing things up scientifically. We all remember Auschwitz being called the place where 6 Mio. Jews were killed, or Dachau another place of mass extermination (concerning gas chambers). We remember myth about RJF soaps to contain the human fat of murdered jews. Lots of these erroneous accounts have been clarified, Auschwitz is one good example, Katyń is another. Anyway there are a lot of gravesite you can unequivocally count to the Nazi ones taken all evidence you can find. Again, most deniers would not even think about denying this fact, cause they would have to deny the crematoria as well. And honestly, why would they? They don´t need to deny them to claim there was no holocaust. I guess you didn´t understand that and unfortunately tapped into this argument. And I guess something else: After leaving this thread and letting some time pass you won´t ever think about referring to the "gravesite-argument" but still go on denying the Holocaust. This would of course proof my argument made at the beginning. I think there is one basic reason why you are here opening this thread: Fear. Otherwise you would have done the research on your own, including accounts of other denier that would actually admit that there are graves.
