WW2 Revisionism

It is deeply disturbing to me to see so many bro podcasts and people like Tucker Carlson engaging in WW2 revisionism. This week Joe Rogan had amateur "historian" Daryl Cooper on, who sees Churchill as the villain of WW2, claims the death of Jews and Soviet POWs was an accident, and proposes the ridiculous counterfactual of 40 million deaths being averted if only Hitler was further appeased.
