I don't think there is anything wrong with wishing that racism wasn't a thing. The problem with the "I don't see color" mentality is that people use it as an excuse to ignore the examples of racism around them, because in their minds, everybody is equal therefore there are no problems. It ignores the reality that race is a very real thing in America that can influence jobs, success, and a lot of other things. It also stops a person from realizing that perhaps they aren't as unbiased as they think they are.
I used to be one of those people that didn't see race, and yet, I still had horribly racist views as a result like "racism is over, it's THEM that are the problem, and even racist, because they keep talking about race".
Anyway, I don't think you meant any harm.
