There are reasons to worry about right-wing extremism taking violent forms these days.
The fellow who shot up the Unitarian Church in Tennessee was a huge Hannity fan. He believed liberals should be killed because they are ruining the country.
His views are in line with those of Ann Coulter in that Coulter "thinks" that liberals are guilty of a crime that carries the death penalty. (Coulter wrote a book about the matter called "Treason").
I'm on an internet argue board where two right-wingers have talked about killing Democrats. It's unlikely they would actually do such a thing but they claim to have the firepower.

Seems things remotely related to right-wing anything has become a basis for putting that item under a federal microscope. To me this kind of activity only demonstrates, fairly clearly I might add, it's the administration who is actually afraid of "we the people" who are simply fed up! Merely saying you have had enough is politically spun to mean you are a threat, you are (or MAY become) violent, or off your meds! Too funny!! Welcome to the new Amerika, commrads! I hope you (and I mean every citizen!) enjoy the change which has arrived.
