I saw a photo of a white kid and his black friend having the same haircut so they their teacher couldn't tell the difference. I guess that was supposed to be proof that kids don't see race.

I doubt that is a good idea. If that white kid grows up to be weaker than the black kid, I am sure that the black kid will start to bully and harass him. Most black kids are extremely violent and hateful towards people that are better than them. That is my experience.
