Agreed. Unless it's supported by a legal framework, racism is a self-defeating phenomenon. Racist individuals deprive themselves of the benefits offered by the group toward which they are racist, therefore making themselves less likely to succeed. If anything, a person or group of people being racist should alert you, the observant seizer of the day, to an under-utilized resource and/or market niche.

So long as big brother isn't enforcing it; another person's stupidity can always be turned to your advantage.
