The Holocaust is one of the most well documented and researched periods in history. There are clear records of the systematic and industrial scale of the Nazi plan to murder the Jews of Europe. Not only from historians but from the Nazis themselves. Most importantly, we have the testimony of the lucky few who managed to survive whilst their families were shot into pits, deported and sent to gas chambers or simply left to starve to death.
You would therefore think that those who seek to deny or to denigrate this history would be given short shrift.
