Don't watch him and never heard of him before but going off on his video titles+thumbnails, this seems like average breadtuber stuff which is like some guy making 'video essay'-adjacent videos either constantly rebutting right wingers and/or just dipping their toes into leftism while researching their video topic. Not actually familiar with any serious theory, spotty and/or dubious citations, doesn't like AES, engages more with rightwingers (even if it is in opposition) than any 'leftists' because that's the most prominent way to get views on youtube, that kind of 'breadtuber'
LOL I'm literally 1 minute into ' "Socialism Always Fails": A Dishonest Claim (3 Times It Worked) ' he literally says "I do believe old communist states devolved into tyranny and state capitalism". Then he echoes a bunch of common anti-communist "leftist" claims like that the bourgeoisie wasn't dismantled and the state just replaced capitalists in subordination of the proletariat; USSR is technically bad because human rights violations; and nobody should look up to (my guess is this includes reading or studying... come on) Stalin or Mao and also throws Pol Pot in the same group as them (the insinuation I'm getting here is that he buys into the narrative of "holodomor" or kulaks or great leap forward or cultural revolution are actual genocides of which includes the Cambodian genocide). It's somewhat disappointing but also funny that I had him pinned... these types of anticommunist "leftists" like to have this moralist/perfectionist position where successful socialism is when you never ever make mistakes, or rather, don't survive long enough to make them because their projects were cut short due to intervention (the 3 he names as "worked in the past" are Sankara's Burkina Faso, Arbenz's Guatemala, and Allende's Chile). idk, maybe come back in a few years and hope he gets serious like 2nd thought.
I'm assuming that notion is based on primarily proselytizing missionaries. Some of the Qing emperors flip flopped on allowing missionaries (foreigners) to do their evangelizing (so, if the "China persecutes Christians" is some anti-communist "commies oppressing freedom of religion!" angle then yes that's a lie or at least an exaggeration, because China's relationship with religions - in general and not just Christianity - has a ton of history. Also see other replies on the permitted Christian sects list in other comments regarding today's PRC). In more recent/modern history (may fourth movement known for anti-imperialism etc) that missionary stuff is seen by some as a foothold for colonizers, but also during the Republican era missionaries were sometimes allowed in (think Pearl S Buck's family) and were also faced with getting kicked out later as the tides changed.
