Skyman!
For ex: history say's more Jew were killed than there was actual jews alive at the time ;millions survided. ;Proof for this is taken taken from actual census before the war. The gas chambers said it have killed so many Jews have been studied and the Gas chambers would not of done the job of killing them.
You are wrong! These exact arguments are what the "revisionists" say, I have discussed a lot with them, because I used to have very right-wing sympathies! Yes, you all heard me, I used to be...well, not a nazi, but very right wing. I am still very much against immigration, especially from moslme countries, but I don`t consider myself extreme right-wing anymore. About the arguments you mentioned! "Revisionists" (is a pseudo-science, by the way) base your first point, "that there weren`t even 6 million jews in Europe at that time" on population statistics that are many decades old. Modern research shows that the jewish population of the world before 1939 was around 16.5 million. Around 10 million of these lived in Europe at that time!
In your second point, you didn`t even get the argument right! Noone, not even the most hardcore nazi/revisionist has ever claimed that the gas chambers couldn`t have gotten the job done. The argument is that the crematoria ovens couldn`t have gotten the job done! And they are wrong! If you`d like, I can explain you why (it takes time, though, it`s a big issue). Please be more careful where you get your sources!
The facts are: Noone knows exactly how many jews dies in the Holocaust! - but it is more probable that more than the estimated 5.5 million died, than fewer! In the occupied, eastern territories alone, the Einsatzgruppen (A,B,C and D, in total approximately 3000 men, serving under SS-commando) killed 1.5 million people (jews and political commisars) by shooting! another 4.5 million is estimated to have died in the death camps, of these, around 2 million died from disease, starvation and sporadic executions/hanging etc. The rest (mostly women and children under the age of 12) died in the gas chamber. In Auschwitz-Birkenau, Treblinka, Sobibor, Belzek and Majdanek, children and their mothers, along with old people, were liquidated immediately after arrival.
