There's a statement for you.
Why is there a KKK and why isn't the government doing anything about it?
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.
