Paul Krugman says "So, let’s try another shot to the head."

I realize he's talking about a misconception, and he has designated the misconception a "zombie," and according to zombie lore, zombies are destroyed by shooting them in the head. But still. That's quite a violent way to talk about the thoughts in the minds of the people you want to correct.

And it was just last January that Kruman, responding to a terrible shooting, wrote:

So will the Arizona massacre make our discourse less toxic? It’s really up to G.O.P. leaders. Will they accept the reality of what’s happening to America, and take a stand against eliminationist rhetoric? Or will they try to dismiss the massacre as the mere act of a deranged individual, and go on as before?

If Arizona promotes some real soul-searching, it could prove a turning point. If it doesn’t, Saturday’s atrocity will be just the beginning.
