> I'd love it if racism were to just disappear too. But wanting it to happen doesn't make it happen.

The point being made here is that making the system even more racist is going to make the problem even worse. It's bad to assume Neal DeGrasse Tyson is a shoplifter because of the color of his skin. It's also bad (it may or may not be worse, but it is in no way good) to assume a person will discriminate against others because of the color of his skin.
