Oh here we go again. I refer to the evidence and bona-fide papers and articles, and I give explanations you can understand, and you just take the that's not evidence line, you've provided nothing. Reminds me of when I was telling a bunch of YECs about fossils and strata and carbon dating. All they ever said was that's not evidence, you've provided nothing.

In the real world the ferromagnetic material rotates.

In the real world a Dirac spinor isn't called a spinor for nothing.

Not so. I've referred to electron models which have received scant publicity and which people like you dismiss. Because it doesn't fit in with your textbook bible which tells you the electron is a fundamental particle, don't worry about pair production or magnetic dipole moment, it's all just intrinsic point-particle magic.

I haven't tried. And I'm not minded to. See above. We can't get past first base on E=mc˛ or the electromagnetic field, so I don't think we'd get anywhere on what sort of a wave equation we have or what kind of current we're talking about or what a spinor is and how the hard scientific evidence tells us what we're dealing with. Besides, if I did come up something that Dirac said to support my case, lpetrich will dismiss it as text-thumping. There's no point, I'd be knocking myself out on what would turn out to have been a deliberate distraction with no sincerity behind it.

Mesons are seen, jets are seen, but we've never seen a free quark. And remember that gluons are virtual particles. They aren't real particles. Remember that when you think of a quark-gluon plasma. Note that "the resulting matter does not behave as a quasi-ideal state of free quarks and gluons, but, rather, as an almost perfect dense fluid." Note this too: "some mesons built from heavy quarks (such as the charm quark) do not dissolve". See the words fluid and dissolve? A quark-gluon plasma is a bit like pea soup. There ain't no peas in it.
