Stop use the word tribalism, kthx
And here's a twitter thread that explains what you actually mean if you're saying tribe anyway
and as it says, Natives can say tribe. this is for all the rest of y'all and the weird ways you say that word and related terms. It's really... gross honestly.
"Tribe" is also a terrible way to mush together social, legal, governance and kinship systems. A bit like using the same term to cover "the city of Munich", "the clan MacDonald", "Flemish people", and so much more.
A community that skews thoughtful and weird. Everyone who abides by the code of conduct is welcome, thoughtful weirdos most of all! :)
