To me, color-blindness means "I don't see you".

Color-blind has a very negative connotation to me, as it is simply of form of blindness, which is the original meaning of the word, literally not being able to see color. If one was literally not able to see color, this in and of itself would do nothing to rid the world of racism. To do that, one must see, and see everything. The biggest problem is ending racism is that people don't see it.

Claiming color-blindness is an easy out. It does not require that one actually engages with someone of another race in any meaningful way.
