The best indication that "Shakespeare" didn't write those plays is the name itself. As far back as Elizabethan times, a "spear shaker" was a third-echelon player, below even Supporting Cast: a human presence on the stage who had to be there just because someone had to be there.

I think that’s probably an urban legend, but anyway, he didn’t even use that form of his name himself necessarily.

He had his father John Shakespeare take the name for the same reason, a man who was a glover?

If that is your best argument I find it unresearched and unpersuasive.

He was born and baptized with that name, long before he was ever involved in the theater.
