There is nothing more dangerous than a little knowledge.

Frankly, this turd isn't worth the anxiety he causes you, I don't care who he is. His word isn't the Gospel, especially since he knows so little about any of this. Try to avoid him as much as possible, but when you can't, don't let him push your buttons. He does that because he's as emotionally mature as a third-grade playground bully---he's waiting for you to react.

Believe me, he doesn't deserve to rent whatever free space is left in your head after dealing with your schizoaffective-bipolar combination....Next time he tries to start an argument, consider the source and walk away. Eventually he'll get the hint and move on to easier prey.
