On reflection, I'm hard pressed to recall even that single instance of Friedman being caught "wrong" and provoking the remembrance alluded to above. Maybe he could give me an example... he would, you see.
Still, this aforementioned vituperation is handily dismissed with citation and then calmly endured. Dogs and spots, you know. Another metaphor: a gentleman's gentleman, a sober butler of the ufological; Mr. Wayne's Alfred, if you will, but we're stretching.
The preceding precisely explains, I suspect, a lot of vituperative angst on the issues extant. Remains, Friedman makes a regular substantive contribution.
I'm going out of my way to be civil, here, reader.
