Sometimes Einsteinians are not lying - they are just incredibly silly:

http://motls.blogspot.com/2013/09/confusions-about-relationships-of.html
Lubos Motl: "All other theories must be made compatible with the two postulates of special relativity: *Relativity postulate: the laws of physics have the same form in the coordinate systems of all observers moving by constant speeds in a constant direction (inertial frames). *Constancy of the speed of light: the speed of light is constant, c, regardless of the speed of the source and the speed of the observer. Maxwell's theory of electromagnetism was actually compatible with those principles before relativity was found; that's why Einstein's good understanding of electromagnetism helped him to discover special relativity. However, ordinary mechanics was only compatible with the first postulate (which is referred to as the Galilean invariance in non-relativistic mechanics); it didn't respect the constancy of the speed of light because the speed of light was supposed to become c±v if an observer was moving relatively to the aether ? a preferred environment in which the speed of light is c (independently of the speed of the source!) ? by the speed v . The 1887 Morley-Michelson experiments made it clear that the speed was always c, regardless of the speed of the observer."

What Motl the Einsteinian should learn:

1. Maxwell's theory was not compatible with the two postulates - according to that theory, the speed of light (relative to the observer) varied with the speed of the observer.

2. If by "ordinary mechanics" Motl means Newton's emission theory of light, then "ordinary mechanics" had nothing to do with the ether - according to the emission theory, the speed of light varies with the speed of the emitter just like the speed of bullets does.

3. The 1887 Michelson-Morley experiment unequivocally showed that the speed of light varies with both the speed of the emitter and the speed of the observer, as predicted by Newton's emission theory of light.
