An Einsteinian demonstrates how both the speed of light (relative to the observer) and the frequency vary with the speed of the observer but then explains that only the frequency varies (the speed of the light doesn't):

"Light frequency is relative to the observer. The velocity is not though. The velocity is the same in all the reference frames."

In Einstein's schizophrenic world the old principle of Ignatius of Loyola is valid and Einsteinians strictly obey it:

Ignatius of Loyola: "That we may be altogether of the same mind and in conformity with the Church herself, if she shall have defined anything to be black which appears to our eyes to be white, we ought in like manner to pronounce it to be black."
