The great identity problem the right seems to be having at the moment is not about whether they are complicit in these particular murders, but whether it’s plausible they could have been. That’s especially true since Glenn Beck has rhetorically encouraged violence against groups and individuals, and, as Media Matters’ David Brock points out, some nut has followed up. It’s not whether people like that knowingly stoked Loughner’s particular incoherence, delusion and detachment from reality but whether far too many of them have exhibited the same dangerous fantasies and eliminationist tendencies in their own statements and writings.
