Yeah I've noticed he likes other Japanese media and things like their music and some of their games (which he's surprisingly okay with turning off his anti-anime bias for), was not aware he lived in Japan though.

In terms of his Lincoln video, some historian youtuber did a pretty brutal reaction critique on it (though I don't agree with all of his criticisms, some were pretty dumb/unfair, but he did have several good points and pointed out several holes and lack of strong sources in Razor's video).
