Eureka! I think I have finally discovered the source of your “mystique”. You think “relativist” means something that differs from the manner in which I have consistently used the term in this thread and, being unwilling or unable to comprehend my use of it, rather than ask me to define the term, you’ve decided that there is only one way to use it: yours. That, IMO, is funny.
Here’s the title of a book written by Albert Einstein in 1916 and revised in 1924: Relativity: The Special and General Theory
I have no idea what word you would use for someone who accepts and believes “Relativity”, as Einstein uses the word. Me? I’d call such a person “a Relativist”, which has a history over 100 years old. And I’d call a person who reject’s Einstein’s Relativity, “an Anti-relativist”, which has a history at least 15 years old, if not more.
My guess is that you’d be mystified by the title of Eric Poisson’s book, published in 2004, A Relativist’s Toolkit.
Some day, see if you can lay your hands on a copy of Milena Wazeck’s book: Einstein’s Opponents: The Public Controversy about the Theory of Relativity in the 1920s . Translated by Geoffrey S. Koby. xxi + 355 pp., illus., bibl., index. Cambridge: Cambridge University Press, 2014. Then look through and find all the uses of the word "relativists’. Here’s the first instance, in the opening page of the Introduction (Page 1):
Prague, October 1913. Oskar Kraus, an associate professor of philosophy at the
German University, sends alarming letters to Ernst Gehrcke, a physicist at the Reich
Institute of Physics and Technology in Berlin: “People are suffering from extreme fatigue, and an irritability that is due not least to the absurd theories of the relativists. I have a burning desire to see the source of error revealed for all of the absurdities that you yourself, honored sir, have accurately characterized. I also see that you have already revealed internal contradictions and absurd consequences multiple times. But where is the source of error? Because despite my calculation errors, I am still able to recognize the fact that the theory of relativity is false.”
