Maxwell's equations of electromagnetism are considerably harder to grasp than special relativity, they certainly stopped me in my tracks. Which is why I suggested taking the postulates as given for the purposes of this discussion.

I believe that there was already experimental confirmation of the constancy of the speed of light by the end of the 18th century, even before the Aether had been dealt a death blow, or at least results which made more sense under the assumption that the speed of light was constant for all inertial observers.
