ROTFLOL....you are not responding because you don't have a valid
argument. I am not going to respond the rest of your post until you
admit that Einstein did stipulate that the lightning strikes occur
simultaneously and that:
1. the track observer sees them to be simultaneous because he is not
moving wrt the light fronts.
2. the train observer sees them to be not simultaneous because he is
moving wrt the light fronts.

In SR, "not moving with respect to a light front" makes no sense.

But that's what Einstein assumed for the track observer. The
simultaneous light fronts are moving isotropically c toward him and he
is not moving wrt these simultaneous light fronts. That's why he sees
the strikes to be simultaneous. OTOH, the train observer is rushing
toward the front light front and receding away from the rear light
front and that's why the train observer does not see the strikes to be
simultaneous.
