We'd have to see how ACLU-members react/reacted to transgressions of friends or allies vs opponents. Would they not be affected when evaluating e.g. corruption charges? It'd be very rare.

Defending both left and right against the government is another story, I think. There are more tribes than just left and right, and even left and right I'd see more as meta-tribes, tribes made up of other tribes. Depending on the issue you're looking at, alliances shift, e.g. on Ukraine or Israel where the fault lines are not the typical left/right divisions in most Western countries.

That "law" probably resonates with lots of people who aren't fans of conservatives, but that's a low bar to clear and doesn't say much about whether it's true and only conservatives form tribes (calling everything conservative that forms a tribe would turn it into tautological reasoning). Every political movement I've ever witnessed was tribal at its core. I'm not sure it's impossible to have a cohesive movement without forming a tribe, but it doesn't seem to be easy or we'd see it more often.

I don't think 'Tribe' is really defined as merely a "political" group in the OG article. It's more a system of government rather than political affiliation. In tribalism, it is rule-of-the-strong, dominance over the weak; it is not 'rule of law'. Any group that believes in rule of law rather than dominance of the weak is not tribalistic. The article posits that the shift of tribalism comes about as a group can tear down the barriers that the rule of law provides - at which point society readily devolves to tribalism.
