A clown is someone pretending that 3 can be 4 for some obervers.

 This is not exactly what I am saying.

This is exactly what you wrote.

In short, for A, tB and tA' are simultaneous.
I repeat, for A, tB and tA' are simultaneous.

Numbers like t_B or t'_A cannot be "simultaneous". Events
like e1 = "B sends back a light signal to A" or e2 = "A receives
this signal" can be.
If this is what you meant, which is likely, then, according
to Einstein-Poincaré *definition* of simultaneity:
e1 and e2 are NOT simultaneous for A (nor for B)
If your definition of simultaneity says so, it is broken. You
even noticed that is broken.
Switch from your asinine definition of simultaneity, which is
broken, to a correct one.
