Sorry, but I disagree. Slate didn't go "off the reservation." They were chiding the leftists, letting them know where they screwed up, and telling them they need to do a better job of covering their trails.

Good point. It reminds me of a technique that Rush employs on occasion. He will start to say something and stop, asking himself (rhetorically) if he really wants to impart this important information that the enemy could use. Then he proclaims, “No - it’s OK - they’d never take advice from me, no matter how much it would help them!”
I’m just amused that another one of the Øbozo Propaganda Centers is scolding their own.
