It's time to make racists, Klan members and Nazis afraid again.

Groups like SPLC are filing suit against organizations that foment violence, and the leaders of those groups, with the goal of bankrupting them, and seizing whatever meager assets they have.  If enough people are crushed in that manner, this Nazi issue may calm down a bit. 

Free speech is OK, but violence is not.  People who commit violent acts will not only be arrested, but they will find that they and their families will be driven into abject poverty.  Good riddance to them.
