"I had a raging political argument with my family over Xmas dinner" megathread

Not an argument but my leftist dad has been obnoxious since he came to Taiwan. He's never forgiven them for aiding Guatemala's right-wing dictators. So he keeps making jokes about Taiwan being the rebellious province of China in front of my wife's family. Thankfully she's the only one in her family that can speak fluent Spanish and just chuckles at them.
