Now, we have arrived at another Martin Luther King Day, the birthday of a man gunned down by a right-wing extremist more than 40 years ago and, while we talk endlessly about rhetoric, we have done a remarkable job of ignoring the growing pile of bodies. The murderous right wing is still with us. The racists and the skinheads and the neo-Nazis are still here. Sales of Glock semi-automatic guns are skyrocketing in the wake of Tucson. The growing piles of bodies is real evidence of growing extremist activity. What could be plainer or starker?
