"We learn that the right doesn't even recognize the irony of its claim of being unfairly blamed for the violence of others, when it has spent the last several years doing exactly that to Muslims -- particularly American Muslims. We also learn that the right can simultaneously insist no political party or inclination can be blamed for Tucson -- while it itself blames the Democratic party and the left, for Tucson. We learn that the right does not understand that if you -- if we -- foment a political environment in which politics are to be settled by violence, or the threat of violence, or in a rhetorical tide of violent imagery, it no longer matters what those politics specifically are, or if the hearer even understands your politics or agrees with your politics -- he may hear only the permission to be violent. And ultimately we learn... this template of what the right would do in an actual open-and-shut slam dunk case in which a partisan of the right attempted to kill one of the left. The right would blame that victim, blame him or her for not having brought enough security. Or for not having brought a gun."
-- Keith Olbermann on much of the American right's response in the wake of the Arizona shooting and the call for more responsible political discourse
