Oswald was a lefty. It's seriously time for society to grow up as far as the JFK hit goes. An insignificant nobody snuffed a POTUS. With the exception of JW Boothe, that's pretty much the pattern of political assassinations in the Great Satan.

I'm sure for every piece of "violent" imagery from the right, a comparable could be found on the left. Of course, the definition of "violent imagery" would be a little subjective from side to side. Pimping fear of "the other side" is always a lucrative project.
