Perhaps I ought to give a further explanation, lest my previous post be misunderstood as being in support of racism and all other -isms:

I see it as no different from how we teach our children to be. Say, not to steal. Now, we could say "don't steal, because if you get caught you will be punished". This is the politically correct way, in my view, based on legislation of behaviours.

But I preferred to teach by saying "don't steal, because it is not right; not fair on others; and not fair on yourself either, to know that you have benefitted from harming someone else".

Raise the ethical standards of a society, and the right behaviours will follow. Change the behaviours alone withoput paying attention to the feelings behind them and all you are doing is creating a powderkeg.
