Animus probably. Embarrassment??? NEVER! No one appointed you to be the thread police. No one likely will. No one is stopping you from posting whatever you imagine relevant. You get to control your speech but no one else's. Also take your "lecture" and put it where the sun shineth not. I react to what you post here and I am not going on a search for whatever you have posted elsewhere. I don't regard you as sufficiently important to go to such lengths. IF you do not express yourself clearly on a thread, that imposes no obligations on others responding. Feel free to prove your bona fides by bashing Romney if that is what you now CLAIM to be your position on Mittler. Or not, as you see fit.
BTW, for someone whining as the self-appointed thread police over the posts of others being somehow a problem for not genuflecting to defenses of Mittler, you sure are prolonging your own self-expressed agony by doing precisely what you complain against.
