Who cares what the chuckleheads are saying? Better to ignore them and focus on substantive criticism. Attempting to divine the motives of morons is a waste of time and it distracts from issues that really do matter (of course, for some, that's exactly the point of focusing on the stupidities of extreme positions—they divert attention from genuine problems).
But there are always chuckleheads in the comments smugly sowing distrust in all news media, journalism, and independent free press.
