What distinguishes the Holocaust from any other mass slaughter in the history of mankind is not, that it was against the Jews, not that so many people were killed, not that it was racist.

It is the systematic side of the holocaust that make it so unique. The indiscriminate, bureaucratic and therefore predicatable, factory killing of people that were deemed unworthy of living by the democratically elected Governance of the country (this includes: Gays, Roma and Sinti, Jews, to name the three biggest groups).

People knew why they were being procecuted, because they had been classed as subhuman, there was nothing random about it, it was state philosophy, all machine cogs of the apparatus worked towards it. Independently, maybe, without order, maybe, but with the clear understanding and blessing from the hierarchie.

Thank you Marek for making it clear that Holocaust denier don;t have to be rascists, but very often are - since their motivation is to denigrade the experience and existance of suffering among people that they couldn't care less about.
