That is the whopper he uses as his example???? Granted that was a mistake but it still seems like a fly on an elephant compared to others he could have mentioned.............
Intentionally, I'm sure. By putting on the appearance of introspection, it shores up the credibility of all the propaganda fables they DON'T mention. "See, we're very careful to watch that what we say is true, and we catch ourselves when we get out of line. Nothing to see here. Certainly no anti-freedom bias."
Also note that they carefully picked a case that wouldn't cast doubt on any of their sacred collectivist anti-rights government-sucking shiboleths. ("Gun control", unchecked immigration for anyone who might vote Democrat, Tea Party are evil and racist, expansive intrusive government in general, etc.)
