The KKK is not isolated to the southern states. We have various neo-nazi and white supremacist groups in just about all 50 states. Some racists apparently don't like the heat.

And please, if this is going to be a serious discussion, let's not confine this to the US. There are plenty of racists in Europe as well, at least amongst the football fan(atic)s and the various nationalistic parties.
Only white people are racists and racism only exists in the Western world...?
