The left is just as guilty of using martial terminology in their campaigning. They have maps with crosshairs too. There’s even a liberal map that has Giffords under crosshairs (Giffords after all, was a conservative Democrat).
The shooter is hardly a right-winger. A friend describes him as left wing, and he lists The Communist Manifesto among his favorite books. He is simply crazy.
Let’s be clear: the Giffords shooting was not the American equivalent of the Salman Taseer assassination. And Jared Lee Loughner is not the equivalent of Nashi, Russia’s state-sponsored ultra-nationalist youth group. This guy is a John Hinckley with lower ambitions.
