You need to agree a safe word. That might then allow you to catch up with siblings

If the conversation turns to a point of view where it’s two brick walls then “penguin” or whatever word works.

Have you ever watched All in the Family?

I try to not talk to my mother about politics, because any thime she's proven wrong and not coming to that conclusion on her own, she gets very emotional.

On the other hand, I like to make sarcastic remarks to her boyfriend on social media, where I exaggerate his political views to their logical conclusion. He's very convinced, that the anti-LGBTQ movement will stop at removing gays from public life and using the "magical" cure on trans people, and not at publicly lynching people for not having kids by 30, due to how hegemonic heterosexuality works.

Political disagreements with my dad would have been along the lines of: who was the best revolutionary, Trotsky or Ho Chi Minh?

Ha ha.
