Adam Something is maybe not as far left as to satisfy purists, but he is reasonably far left to seem to be a decent person and not be an extremist. I find most of his videos informative, and I think his last one – a length-ish take on Ukraine’s conflict with Russia, is very good.
Adam Something is a Hungarian Youtuber currently residing in CZ (these are public pieces of information that he himself has disclosed on his YouTube channel). That might explain why he, whilst being a leftist, is very critical of both current Russia and the former USSR empire. He does not have the personal experience with the failed socialist experiment of the last century that I have, but the cultural memory is still fresh. Thus he shares my deep dislike of tankies.
The cold war was not a conflict between good guys and bad guys, just between two different types of bad guys. And that has not changed, at least as far as the current proxy conflict between USA and Russia goes. For some baffling reason, there appears to be a sizable amount of people who think that because the USA was the bad guy in every conflict for the last 75 years that it makes their opponents into good guys.
