Hear! Hear!

Of course the position you've taken is easily-verified, but thank you for
"getting on your [high] horse". There's so much tragic ignorance being
aflicted, in particular, upon Children that just contemplating it is
physically 'painful'.

BTW, your "London cabby" example is extremely-informative in light of NDT's
reification of the "internal frame of reference" [IFR; see my previous reply
to John].

The Cabbies are 'required' to exist in a relatively "passive-phase" {AoK,
Ap5, 7 & 8] experiential realm because they must 'move toward' acting upon
instructions received from external sources. TRhe structural 'divergences'
to which you've referred =definitely= derive in this one thing [which has
been reified in NDT for more than two decades [1974-5 academic year]].

Analogous structural 'divergences' will be observed all over the place, and,
if folks look for them, the position you've taken will =definitely= be
sustained [and the Error of pointing-the-finger-of-'abnormality' at such
structural 'divergences' will be Corrected - and, more-importantly, the
generating experiential dynamics will be [gradually] transcended as the
'guesswork' that has dictated to prevailing analyses is eliminated].

HURRAH!
