Not unusual. TH sometimes makes an effort to weed out the trollbots but - unlike libs -are not into censorship. Trolls sooner or later post their garbage and we are forced to respond to it. We know about not feeding the trolls but we also know -from bitter experience -what happens when their tripe goes unanswered. Not being a lib myself it would never occur to me to go to HuffPo just to cause trouble on their comments sections.
