Your thing looks like Scientology.
It's not by constantly repeating the same blunder that it becomes a truth.

There is a symmetry, and a reciprocity in relativistic physics (there is 
no ether, no privileged frame of reference, and no privileged point 
either, the reciprocity of effects is total).

But you confuse the forward speed of light, and the return speed of light. 
You think that reciprocity and symmetry are there.

That light moves at the same speed for A as for B regardless of the 
direction of approach or flight.

This is forgetting the notion of anisochrony, which Einstein sweeps in 
front of his door, without even glancing at it.

The reciprocity is that it flees A in the same way that on the way back it 
flees B, then it approaches A in the same way that on the way out it 
approached B.

But to affirm that the speed is the same in both directions is false. It 
is only partially true for an observer placed far away, and on a 
perpendicular.

Perpendicular which will change angle by change of reference frame 
(Lorentz transformations).
