When presented the equation t'_A - t_B = t_B - t_A your reaction was that
this equation meant that both clocks tick at the same rate. Which is utterly ridiculous.

You lie.

 Let's check then:

In accordance with definition the two clocks synchronize if

Parce que l'équation dite ici dessus, c'est ça.

  Translation of what *you* wrote about "t_B-t_A=t'_A-t_B." :
     " Am I dreaming here? Einstein said that clocks are synchronized if
      they tick at the same rate??? Is it what you mean?
      *Because the equation above means that.* "
 I'm definitely not lying.
