Mei has shown that the Schwarzschild metric implicitly has the starlight
going through the Sun. You have not demonstrated otherwise, As Einstein
is famous for, you have only engaged in straw man tactics and are
begging the question.

You haven't understood that Mei has shown the Schwarzschild metric does
not give twice Newtonian, so GR does not predict it.

You haven't understood that a false derivation cannot provide a
prediction, so no evidence can be adduced.
