Since both perspectives are of equal rights, we need to accept both views as valid, hence need mutually symmetric perspectives.

Thanks.
But this is obvious and certainly not disputed.
But Einstein, however, had not written about a symmetric system of clock synchronization.
Liar!
« We assume that this definition of synchronism is free from contradictions, and possible for any number of points; and that the following relations are universally valid:
1. *If the clock at B synchronizes with the clock at A, the clock at A synchronizes with the clock at B*.
2. If the clock at A synchronizes with the clock at B and also with the clock at C, the clocks at B and C also synchronize with each other.

What is point 1. if not *symmetry*?
Instead he used something, one could call 'external time' (kind of 'true time').
Definitely NOT!
