Nonono, I was saying that Chris thinks that, if you're not black, you're white. So he would be associating all groups that aren't black with white.
But of course, he can't distinguish black people from other groups by anything but skin tone. Maybe an afro might tip him off, but otherwise, Chris can't notice anything subtle, like facial characteristics. It's like how he also doesn't notice subtle differences between the sexes. He doesn't notice that women's bodies have wider hips than men, or things like that. The best he can do is: boobs? check. no dick? check. it's a woman. (heh, and if you have boobs, but still have a dick, you're a woman-in-training, like Bailey Jay from the mailbag emails)
I think that the best Chris can do is skin tone, and when you get dark enough, you set off Chris black person alarm.
