I agree with the social utility aspect. Yet, I still have fears, especially as a minority, that I am getting one reaction to my face and perhap an entirely different one when I am not around. I'm sure that I am not the only one who feels this way. I expect people to be racist until proven otherwise. And even then you can never be sure. I doubt that this will ever change.
The Germans may say that they are no longer racist but the fact of the matter is that neo-Nazi party officals continue to hold seats in their Parliament.
