I heard this once before, but I forgot the word for it. I've already tried to searched it on google but I could not find anything useful.
"Tribalism" is a new word to express the political bubbles people are living in. And you can easily identify someone's "bubble" by their vocabulary. For example, left-wing people might say things like "oppression, capitalist pigs, racist, homophobic" while right-wing people usually don't.
I would like to know the name of this act. The act of identifying someone's group by their vocabulary.
