Firstly “gorillion” is a Pol inside joke. It isn’t a number, it actually means “the person using this word is a cunt”
Sorry you got tricked into that, but we laugh at noobs all the time.
Secondly as the historians have been saying since the 1950s, the number is about 5.5 to 5.7 million, most likely. 5.1 absolute minimum, but could be as high as six million, but probably not.
Three million Polish Jews for definite, plus half a million Hungarians, quarter million Romanians (killed by Romanians, not Germans) over a million shot on the eastern fron by the Einsatzgruppen and local help - Latvians Ukrainians Belarus, and Crimean locals all killed Jews happily - could be 1.5 million, probably a bit less. The rest from the rest of Europe - a few hundred thousand here, a few tens of thousands there.
There is unequivocal evidence of mass shootings, mass slavery, deliberate starvation and brutality and deliberately working people to death, unsanitary conditions, disease, and cold, death marches, people dying from dehydration (especially on trains) and for mass murder by gassing with petrol exhaust fumes and hydrogan cyanide.
Deniers here use a few well debunked memes - they lie it was all typhus and the starvation was the allies fault (apparently the allies bombed the supply lines to the camps, but didn’t manage to cut food supplies to the villages next door)
They tell lies about the Red Cross (they pretend internal documents about numbers of German citizens traced to the camps are death totals). They say the Red Cross kept a count - they didn’t. They say they visited all the camps- they didn’t they say the Red Cross have all the camp records - they don’t - they say the Red Cross said there were no gas chambers - they didn’t
They tel lies about census data - actual census data shows a 5.5 to 6 million drop in worldwide Jews, with the massive loss in Europe
It happened. Get over it
