Will people really agree to disagree and move on, though? That certainly hasn't been my experience. Over time I have found that some people can do that. For example, my wife and I actually very rarely agree on political matters, but when we do discuss them I know that neither of us will belittle the other or walk away thinking the other is a horrible monster. But that's rare in my experience. So I only talk politics IRL with people who I know have that ability, and it takes time to feel out who can and can't be trusted to do that. Thus, I don't talk politics in mixed company.

I also think another aspect of the "no politics" rule which is important is that it attempts to preserve spaces where people can just enjoy things. People need to escape from politics and just enjoy the good things in life together. This is important for personal mental health but also social cohesion, as it's extremely difficult to have positive relationships with those you only ever argue politics with. If we don't have spaces which enforce a no politics rule, you can't ever unplug from the madness and that isn't good.
