The primary opposition to relativity came from a scientific community that thought Newtonian physics reigned supreme at every level of physics. Many of Einstein's thought experiments involved attacking the problems that Newtonian physics was unable to resolve with common sense.

BTW, if you studied the history of logic, you would find academic history is filled with cases of pretentious snits in the ruling class who had deep comtempt for the common.

The assumption that elitists are automatically right is as much a fallacy that commoners are automatically wrong.

As for your snide poke at Capitalism ... I would like you to answer a big question: Who is the father of modern Capitalism?

I will give you a hint. The guy who created the ideology called capitalism was a pretentious snit who had a deep contempt for commoners.
