"Probably", and "likely"?  What is presented as obvious is not quite so obvious
to me.  Even what I quote above is true -- and I doubt it -- what about the
exceptions?  After all, probable exceptions are definitely indicated in the
statements quoted here, since I do not see the words "Absolutely" and
"definitely".  I should think that such exceptions should count for something.

I'd prefer not to speak in wild sweeping generalities.  I'd sure like to see
some data and specific examples to back up the rather general and
unsubstantiated claims being made.
