I would generally agree with your summary at the bottom of your post...:)
I think that goes along with “protesting” in general. Yes, we occasionally have “right wing” protests. I have even participated in a few. For the most part, though, “right wing” people are too busy working to be out protesting, and too busy working to be obsessing over killing. Leftists and looneys seem to have more time on their hands, and a lot more anger ... and it leads to them protesting, and rioting, and (sometimes) assassinating.
