Yeah, I dislike strident pundits of any stripe. But in this article/message he makes some really interesting points and apologizes for ever using violent imagery himself. He says it is time to repudiate all of the rhetoric.
"Violence, or the threat of violence, has no place in our Democracy, and I apologize for and repudiate any act or any thing in my past that may have even inadvertently encouraged violence. Because for whatever else each of us may be, we all are Americans."
