The Deprogram

Yknow how the KKK really hates Catholics and by extension hates Mexicans [well, hates Mexicans more beyond just being really racist?]

Imagine the opposite of that. Paxtube is a "tradcath" [read: integralist fascist] and so hates the USA for being protestant and for not being racist enough. Ergo, China is based for being racist [not true, many han nationalists are also mad china isn't actually racist against ethnic minorities].

The noted Nazi stonetoss also makes statements to this effect. It's pure atomized idealism and, imo, doesn't actually factor that highly into their beliefs beyond being edgy

It's a Tradcath account. They have a YouTube channel that posts videos with revisionist narratives about the Crusades, the Inquisition, colonization, and anything that makes the Catholic Church look bad. I assume he's just not against China and is in a right wing space that is otherwise very anti-China, so that's why he's dying on this hill? Kinda weird because most Catholics who aren't on the far left aren't fans of China for interfering with the Vatican's authority to name bishops and for regulating Christian missionary work. I wonder how this guy squares that circle.

The only thing I can suspect is that the Vatican has been more conciliatory towards China in the past decade for a variety of reasons, so maybe this guy is following the lead. But usually Tradcaths aren't huge fans of the Vatican because Trad-catholicism as an online phenomenon, and as a real-world one in a more limited fashion, is more concerned with the aesthetics of the Church than the actual religion. Really, the whole thing is about fetishizing what Catholicism was before Vatican II, i.e. before it was modernized. So usually guys like this have such a reactionary worldview it would be unthinkable for them to praise the PRC, even out of some paleo-conservative sentiment of not wanting the West to interfere with other countries (if they believed this, why glorify the Crusades?).

TLDR: This person is deeply unserious and probably grifting.

It is a form of reactionary nationalism I guess. According to your other post about them, it seems they accuse the US of meddling in other countries' immigration policies. Assuming they were referring to European countries, the account could be capitalizing on the growing worldwide condemnation of the USA. The reactionaries who happen to praise China are often ignorant of the PRC's history and achievements. I guess they could be fascists riding the waves of mass discontent and using our socialist rhetoric for their own nefarious purposes.
