Yeah, most of his racism is directed at Asians from what I've seen. And it's not subtle stuff, he's full 1940's style racist when there's an Asian in a game. So he did a let's play for Sleeping Dogs. It is pretty fucked.
Some of this with Dynasty Warriors, too.
If I remember correctly, he sort of acknowledged it poorly with Sleeping Dogs, where he claimed that it's okay because the game is a parody and you're supposed to make fun of it. Not a good excuse.
