Please go to [1] + [2] searches, while not a big channel on YouTube, ~200K subscribers in politics is kind of big for alternative-media with the top videos getting ~500K views.
And now, please note that every video on China is something like "China is actually doing more for Climate-Change", or "Is China to Blame For Covid-19?" all suggesting China has so many good parts that we missed...
While Israel search result are all about the conflict, ".. The [Media] BIAS", ".. The Death Toll".
While Israel is dominant enough to deserve such critics. The Bias of the channel against Israel and Pro China is a spectacle to be hold.

So I will now go return the straw to the barn because I can't seem to find any strawman.
Beyond that, here in the USA, I don’t know anyone who I would consider both a “China apologist” and a “leftist” (“far” or otherwise) – China has not been anything remotely resembling socialist for at least a generation, and the China apologists I know all vote GOP (or would if they could vote).
Unless by “apologist” you just mean “has a low expectation that China’s political system is going to collapse or radically democratize in the near future, and thinks that some level of economic and diplomatic engagement is necessary despite China’s human rights record”.
So yeah basically the intersection of "left wing" and "thinks the Chinese government is great" (which as you point out is not a particularly large group of people, at least in the USA).
Depending on who you're talking to, the bar to become a "China apologist" is not very high.
