Agree with MoH.

If the British thread-humpers will let me post on-topic...

(If you want to talk about British politics in a thread primarily about a guy in the and his son-in-law in the US, would you start your own thread and fight for the on-top position there? Please?)

No politics seem the way to go. Perhaps there can be an agreed-upon penalty for the first person to defy that rule. Either both sides refrain, or no one does and the evening is ruined.

There are people I know because of music who post so much political/conspiracy shit on the internet that I avoid them. Then, I see them again in Real Life and they're the same fun-to-be-around musicians.

Abraham Lincoln:

"We are not enemies, but friends. We must not be enemies. Though passion may have strained, it must not break our bonds of affection. The mystic chords of memory will swell when again touched, as surely they will be, by the better angels of our nature."

The internet can nurture our worse sides because it's harder to get us to shut up. Family gatherings would likely be a place where people would come down hard and fast on disruptive behavior.
