It's a close call, but the former are both insane and violent.
Did you check out Ramsey Clark's act today? He showed up at the protests in D.C. to lead a chant calling for the impeachment of the Prez. ....and the pro-terrorist crowd lapped it up, of course.
I asked the Klan Pink idiot who would get the blame if the guys really are terrorists and managed to kill a few thousand people? Her answer - GOP foreign policy.
So are the latter. The left beats the islamofascists in the insane department, if it hasn't (yet) approached the violence level recently.
