One of the YouTube channels that I watch regularly is World War Two in Real Time. Indy Neidel, the main presenter, did the original The Great War series, and then moved on to start the new project with friends.
Indy normally does the week-by-week recap of the War, as well as a subseries called Between Two Wars. The first season dealt with the politics and political personalities of the interwar years. The second season, currently in process is called on culture, science, technology, entertainment, and adventure - the people and events that contributed to shape the interwar era, and the time to come'.
There is also another subseries called On the Homefront, usually hosted by Anna Deinhard, which deals with the role of women in the war effort, rationing, and that sort of thing.
Finally, there is the series in the title of this post, War Against Humanity, hosted by Spartacus Olsen, the producer of the entire project. It is not a 'pretty' series. It deals with the horrors inflicted by both sides in the War, from the genocide of the Jews by Germany, the horrors of the Japanese Imperial Army's Unit 731, to the mass killings of civilians and POWs by the USSR and the strategic bombing aimed at killing civilians by the Western Allies.
As I have posted about before, YouTube seems to be on a 'War Against History'. You can read posts about a couple of other channels here.
Remember these quotes, which I often cite:
The most effective way to destroy people is to deny and obliterate their own understanding of their history.-George Orwell
To destroy a people, you must first sever their roots.-Aleksandr Isayevich Solzhenitsyn
At any rate, here is a post by Spartacus Olsen on the problems with a) making 'War Against Humanity, b) giving a fair and balanced view, and c) then having it subjected to YouTube censorship.
