Regarding 6 million figure being mentioned before, I'm not sure specifically what you're referring to but I have seen memes of old news clipping mentioning 6 million Jews being in danger in the early 1900s. But if you read those clipping they are specifically in reference to the Jewish population of Russia which was endangered by either the pogroms or civil war. I did some brief research about estimates of Jewish population in Russia during that time period and 6 million seemed a good estimate. So I'm not sure why news clipping pointing out Jewish population in danger in Russia causes suspicion when 6 million is the estimate of casualties after a war ended in Europe in 1945
