So I take it that nobody openly supports the idea that the earth bound
twin physically ages at a faster rate than the traveler and that this
only occurs during acceleration following turn around?

Can we stick to the topic as to whether or not the stay at home
physically ages at the faster rate during turn around rather than
introduce mind games? Keep things as simple as possible.

A similar thing happens in the twin paradox. While
the two twins are traveling inertially at constant
velocity, each twin can consider himself to be "at rest"

Although the traveler considers himself to be 'at rest' he has
experienced the force of acceleration as he blasted away from the
planet and now sees the universe rushing past him so it is a purely
solipsist, philosophical attitude on his behalf for him to consider
himself to *be* at rest.

When
the two twins get back together, one twin will have
aged more than the other. In Special Relativity,
the twin that took the inertial (constant velocity)
path ages the most.

So you apparently agree with the decade old posting that the stay at
home twin physically ages at the faster rate ('ages the most') rather
than it is the traveler who ages at the slower rate.

It isn't that the acceleration *causes* the differential
aging,

I did not suggest that it does. It is the traveler's instantaneous
velocity during the period of acceleration that, according to the time
dilation concept, creates a physical change in the rate of operation
of *his* clock causing it to progressively tick over at slower rates
depending on his instantaneous velocity but the stay at home twin does
not, as you suggest, 'age the most' and no diagrams on a *** of
paper will convince me otherwise.
