"I'm not racist. The Japanese are just a bunch of [insert disparaging remarks on the basis on race here]"
"Yeah, he's not racist, he's right. Have you seen how the Japanese run their country? Trust me, bro, I'm a different kind of Asian; and probably not one of the ones that hates the Japanese"
Hey, look, I don't see a problem with racism; I'm a racist myself. But I'd really appreciate it if:
A) You made accurate statements about racial groups.
B) Acknowledged that you're being really, really racist right now.
If you're going to disparage people on the basis of their race, then be accurate, and own it.
