You appear to be mistaken. The video we're discussing is by someone called "Bismuth", but you've linked to a completely different person called "Bisqwit".
Bisqwit has some videos that are definitely worth checking out as well. I really enjoyed his NES memory visualizations: https://youtube.com/watch?v=hqDGWfZhitc
He's probably referring to this comment Bisqwit posted in the comments on that video:
> I believe there is an incredible number of counterfeit doctrines and antichrists (Greek word that literally means counterfeit messiah), some more obvious and some more subtle. Islam being one of the most obvious ones.
(It's a reference to Islam at least. Not sure how calling it a false doctrine is Islamophobic; seems like a pretty standard Christian take.)
It's a great video, that must have taken hundreds of hours just to animate, not to mention the research. That the author has opinions I don't agree with or are unpopular is another matter. I can have more than one thought because I'm not 4 anymore. This reflex to stigmatise and virtue signal annoys the freak out of me. Just enjoy the video.
