Am I losing my mind?

I think you first should try speaking with the clinic guy, just like the above threads state. If he won't listen to reason, then just go out and call the games the way the rules say to. When the first player objects when you call it correctly, tell him to show you in the rule book where it says the defender cannot move after becoming set. When he says he doesn't have a rulebook, offer to lend him yours and give him the rule and/or case number.

Then let's see what he says.
