It really sucks that it is literally, impossible to burn that many bodies in such a short period of time.
It really sucks that your fear of Jews make it impossible for you to think like a rational human being.
OK, a town with a population of 28,000 about the size Kennebunkport, Maine can't handle 982 dead in one day, that's about 3.5% of the population of Zittau or the equivalent if 290,000 people per day were dying in New York city. We aren't told what Zittau's capacity is but we should assume that no city is prepared to handle 3% per day death rate. They probably support 2-3 furnaces with a capacity of 8-12 bodies per day.
By contrast, the NAZIs at one furnace alone in Auschwitz boasted of being able to turn 1500 people per day to unmarked piles of forgotten ash. That's one site capable of cremating half a million bodies per year. Auschwitz records claim to have cremated about 900,000 bodies over the space of two years so that fits well within Auschwitz's documented capacity.
I don't know why you piss your pants and feel compelled to tell a lie every time the word Jew is spoken, but understand that mental illness is yours and not relevant to any appreciation of modern Judaism. Please seek help for your mental illness- self-deception will destroy you.
