This is Karl at his most naive. Atun-Shei is a history youtuber that recently took off (the algorithim started to favor him). He's a film and history grad, from somewhere in the north of the US who worked at Gettysburg as a guide then moved to New Orleans.
He worked in new Orleans as a tour guide (despite only having lived there for a few months) then started YouTube. He obviously had some bad experiences with certain groups, firstly pro confederacy types and secondly historical re ennactors because they're the subject of a lot of his early videos.
He was making videos calling various monuments racist back when it was still only barely trendy. He also used to make a big show about how big and powerful a group 'the lost causers' were and how brave he was standing up to them, despite living in the midst of the evil racists.
He owns 3 costumes, one a union soldier (which many people have told him is historically inaccurate) a confederate soldier, and a SS officer, and he gets the maximum use out of all three.
Currently he's doing the progressive thing of calling for donations to 'bail funds'.
Don't get me wrong, he makes well produced content, but he's a typical progressive YouTuber, constantly claiming he's fighting the overwhelming forces of reaction.... while never actually saying anything that his core audience disagree with.
For example on twitter he was obviously upset by Grant's statue being attacked, but he tried to claim it was 'lost causers' somehow provoking it from behind the scenes.
