The common feature among concern trolls and those who whine about civility and the precise tone of political discourse is that they all think they should be able to control the terms of the debate. They see themselves as referees, floating above the discourse and calling fouls where they see them according to some rulebook they pulled out of their asses, rather than participants in that discourse.
And, here we have our pal No Show Joe, once again saying that criticism is okay... when he says it's okay.
What a wanker.
