There are ways to solve this problem. If I can define my pronouns to be whatever I want and you're a bigot if you don't play my game, I can assure you I'll come up with some pronouns that you really don't want to say.

Start with the black supremacists pushing this crap: My new pronouns are: Massah and Massah's. "Ex. Massah says Massah doesn't like tomato on Massah's hamburger. Massah wants a refund."

And I if you run into the bleeding heart variety: My new pronouns are: Mein Fuhrer and Der Fuhrer's. "Mein Fuhrer says you must call Der Fuhrer "Mein Fuhrer" or you're a bigot."

If they want to play this stupid game, give them some very stupid prizes to win.
