That's not as blatant or easily recognizable as "impolite" as calling
someone a "butthead", but it is impolite just the same, albeit more
cleverly so.

Agree 100%. But in that regard, this sort of subtle "impoliteness" is de
rigueur amongst the population in general nowadays. At least its clever,
which is more than you can say about the other trolls here.

Ignorance is not necessarily abated by becoming a certificated pilot.
(Witness the number of pilots who responded negatively to my flying to
Florida VFR using on-board XM weather.) At least MX's ignorance often leads
to good topics.
