*No, that's not it. Rather, I am uncomfortable with de-facto
frame-jumping because I am unsure what happens to time when this is
included in a solution. And if the twins are at rest and juxtaposed as
the scenario begins -- which, BTW, is how the TP is habitually DEFINED
-- the traveling twin MUST accelerate to begin his journey. But in the
final analysis it's "your way or the highway", meaning that alternate
solutions are unacceptable for you. *
Not at all. You think it depends on acceleration. Fine, then here's an
alternate version with acceleration. The twins each accelerates exactly
the same level for exactly the same duration. But Red is still younger
than Blue for exactly the same reason; his path is longer in space and
therefore shorter in spacetime.
*So, if there is acceleration, there is also gravity by applying the
Equivalence Principle, *
So did you apply gravitational time dilation to each twin above?
*and clocks in gravitational fields slow down, and this applies solely
to the traveling twin. Notice, I never used or applied the concept of
force, *
Above you seem to think the equivalence principle means acceleration
implies gravity

*so claiming I did so, shows you didn't understand my solution (using
