This has happened to me too, I have ascribed this to being suggested related content after viewing content relating to current world events.
I've gone down a strange rabbit hole picking some of his videos at random and I'm not sure what to make of him. On the one hand he seems to present ideas similar to what is being discussed on this forum (e.g. Pax Judaica, boomers destroying the world), on the other he has views on religion in general and Christianity in particular that I imagine many people would describe as heretical or anathema (e.g. that the Jews didn't kill Jesus, that the Romans did and shifted the blame onto the Jews, and created Catholicism to support this...)
It seems he came to sudden prominence after Trump got reelected and he made a video predicting this months prior -
The Professor Who Predicted Trump’s Return and War With Iran
My feeling is that he's a very well-read man who is drawing connections between so many things that you'd have to be a genius or slightly crazy to fully understand or believe him.
Basically the Asian version of this meme:
I am deliberately not going to include a hyperlink to his channel because I am actually unsure if it's a good thing for more people to get too involved in his content, though if you believe you're at the right stage in your life to make up your own mind you'll easily find it, if his content hasn't been showing up in your feed already.
