Just wait for a moment of silence at dinner and then be like

"The turkey's not the only thing that's been proven well-done this year."

"Pass the gravy. And while you're at it, pass the epistemic humility."

"It's a shame the only thing thicker than this gravy was the denial in this room twelve months ago."

"I don't need a place at the table to know I've already set it for you with the truth."

"Enjoy the meal. I'll be over here, dining on the most thoroughly vindicated predictions of the last decade."

"The only thing more predictable than Uncle Ron falling asleep after dinner was every single thing I warned you all about."

"This silence tastes better than any truth you've been sold all year."

"You can ignore me, but you can't ignore the rubble of every institution that lied to you."

"I'm thankful for two things: this family, and the painful, undeniable accuracy that keeps me from idolizing it."

"Don't worry, I won't say 'I told you so.' The headlines are doing it for me."
