Einstein's relativity is based on an assumption which is too idiotic, even by the standards of the Einstein cult. For that reason Einsteinians never state it openly. Here is the idiotic assumption:
As the observer starts moving towards the light source with speed v

If the distance between subsequent pulses does not shift from d to d'=dc/(c+v) and remains constant, which is more than obvious, frequency and speed of light vary proportionally for the moving observer and Einstein's relativity collapses.
Einsteinians deal with the problem in different ways. In most cases the scenario (stationary light source, moving observer) is not discussed at all - only (moving source, stationary observer) is discussed. Surprisingly many Einsteinians teach the truth: distance between subsequent pulses (wavelength) remains constant while frequency and speed of light vary proportionally for the moving observer. The only precautionary measure is to leave the variation of the speed of light implicit - the brainwashed scientific community would never make it explicit.
