Interesting post, I really hope this can engender some interesting discussion.

I've been wondering about this notion for quite some time, typically around the idea of political tribalism. Do you think this is a new thing? I'm too lazy to go hunt down the source, but I heard/read recently that as compared to 20-30 years ago, Americans are far less likely to be willing to engage in friendships/relationships with people of differing political views. What has changed?

One theory I have been playing with is that political tribalism has risen at the same time that religious tribalism has declined.

I would like to explore one idea, and would love to get your take. You say one "can't seriously expect ancaps and libsocs to get along and want to spend extended periods of time with each other."

What do you suppose would have to change, in order for this to change? Would we simply have to collectively focus our tribalistic tendencies around something else, or is there some other hope for useful, meaningful political discourse that transcends political ideologies? THANKS!
