double,
what is very sad is that it is impossible to talk logically and civilized about this matter without being acused of being a nazi or whatever crap. just for your info i do not in any way condone what happened regardless of the actual size of the holocaust. it was uncivilized and barbaric like the whole damn war.
also nobody questions the existence of concentration camps, or the tatooing of numbers, the death of a large number of people and the anexation of wealth. however, the actual number of killed people is far from being certain and neither is the number of jews living in the areas controlled by germany at any time during the war. for instance until about 10 years ago it was claimed that 4 million people were killed in auschwitz...this number was then reduced by the polish government to 1.2 million. the ovens you mentioned were incapable of buring the number of claimed victims etc.
this does not make the whole thing a lot better but the true numbers are of some relevance.
also in my opinion there is not a big difference between killing people by gassing them or shooting them compared to killing them by carpet bombardments or dropping of nuclear weapons. so come down from your moral high horse.
in any case what is going on today cannot be justified by what happened 60 years ago.
