Relativity is a sort of esotericism, as when Einstein told the New York Times in about 1920 that only twelve (apostles) could understand it. The problem with that has to do with "to understand relativity as Einstein understood it." Anti-relativists have an understanding as well though it is not the same that Einstein found acceptable. By Einstein's standards they do not understand relativity. I say that they do have an understanding of the topic.
