You didn't provide evidence, or argument, or anything. You did a Farsight-standard "look, read this, and you'll come to the same conclusion I did."

Nope.

The Einstein-de Haas experiment proves that intrinsic angular momentum is a type of angular momentum, and goes into the same conservation law. In the real world, Dirac (among others) was able to describe this momentum without assuming anything "going round", and that's perfectly consistent with all known facts about these particles.

Your mental picture already contained "something going round", and you read about de Haas and thought it agreed with your picture. That's all the argumentation you have here, and indeed it's fairly typical of you.

If "something going round" is so important, why can't you find an error (or a failred prediction) in Dirac's treatment?
