What you call a "lie" is merely a confusion due to lack of precision
and misunderstanding of terms. Let me spell it out to you:

According to Maxwell's electrodynamics, the speed of light is c
relative to the vacuum. Consequently, it is independent of the speed
of any objects, be it emitters or receivers ("observers").

That principle (the "light principle") was taken as second postulate.
The essential point (which you may never understand) is that this
principle is only apparently incompatible with the PoR (which was
taken as first postulate); counter-intuitively it turned out to be
possible to find a theory that combines them, and this theory is
called SRT.

Now, in SRT it is common jargon to call an inertial coordinate system
of reference an "observer"; and relative to that "rest" system of
choice the speed of light is taken to be c, by convention. That kind
of speed relative to the chosen "rest" system (commonly called "the
speed") should not be confused (as you do) with the speed relative to
"moving" receivers in Maxwell's electrodynamics; instead it
corresponds to the speed relative to the vacuum in Maxwell's
electrodynamics.

But will you be able to understand that? I wonder...
