Maybe this was already posted, but Ross Douthat links to Scott's post about scissor statements as it applies to the Covington Catholic high school boys controversy.

When you start arguing with someone over a Scissor statement, Alexander’s narrator explains, “at first you just think they’re an imbecile. Then they call you an imbecile, and you want to defend yourself. … You notice all the little ways they’re lying to you and themselves and their audience every time they open their mouth to defend their imbecilic opinion. Then you notice how all the lies are connected, that in order to keep getting the little things like the Scissor statement wrong, they have to drag in everything else. Eventually even that doesn’t work; they’ve just got to make everybody hate you so that nobody will even listen to your argument no matter how obviously true it is.”
