>>>Someone should sue for liability.<<<
You got that right. The left is constantly using the legal system to advance their agenda and destroy their enemies. Time to be proactive. It would be a delight to see the SPLC on the stand trying to defend their listing of the Family Research Council as a terrorist organization. Sue them for millions, and the stick the head on a pike at the outskirts of town to warn the next stupid bastard not to do it again. Metaphorically, of course.
Even if SPLC loses, it would cost them millions defending themselves.
Be nice to see lefty groups getting hammered by their own tactics.
