One of the most red-pilling rabbit holes I ever went down was researching where the "six million" number originated.

We are told to never forget the six million, so I felt a duty to those who died and the millions of death camp survivors, to understand.

It's a fascinating ride which starts in Russia before leading to military tribunals in Germany, red faces in Poland and end in forensic science labs from a dozen countries. Four becomes six, becomes one, becomes none. Wow, what a ride!
