FWIW Lindybeige is very entertaining but not particularly credible. One sign of this is probably his back-and-forth with Military History Visualized on the debate between the Bren and MG34/MG42 machine guns.
I’d definitely agree with that. I get more of an amateur interested in history (and from a quite strong English bias, at that) vibe than someone trying to present historical research, but it’s good to call that out.
There are actually several (maybe even most/all?) channels above that I would describe as “interesting voices” rather than “credible, non-biased experts” so take them with a grain of salt.
I mean, nothing on Youtube is particularly credible. But at least with Lindybeige you never get the impression he is a definitive source.
History in particular is a field where even trained historians can't help but nitpick each other to death. So I think people should just enjoy pop-history for what it is.
