1228 6 Million Jews?

Without reservation, people accept there were 6 million Jews killed by the Nazis: why wouldn't they? They were taught that as a child, and teachers only teach things that are true, don't they? As far as "The Holocaust" goes, there's a ton of seeming fabrication used for political motives, mostly as a lever to establish Israel. Congratulations, it worked, and the propaganda was admirably done. However, where did that number come from? The concentration camps only accounted for a small fraction. For example, something over 50,000 prisoners total died at Buchenwald, the largest concentration camp, most from exhaustion, starvation & disease, only a fraction of which were Jewish. Even if multiplying that number by the number of camps, it’s be far short of even a million of anybody, let alone Jews. Turns out, the 6 million is derived from the census of how many Jews there were in Germany before the war vs. the census after the war: 6 million Jews lived in Germany in 1933; none afterwards, as if a post-war Jew would admit they were on a public census. Tenuous proof indeed but justifiable.
