可以想成地上畫了一個圈。圈裡是「我們的人」，有我們的頭人、我們的規矩。圈外就是別人。tribalism 有時候指的是這個圈本身，也就是社會真的是一圈一圈組起來的；有時候指的是圈畫好以後，人會變成什麼樣子。這個字的兩邊意思，都可以從這個圈看出來。From the word’s history
tribal + -ism: the suffix -ism turns an adjective into a whole set of ideas and behaviour, so tribalism is 'acting along tribal lines'.
tribal（部落的）加上 -ism。-ism 會把一個形容詞變成「一整套想法和做法」，所以 tribalism 就是「照部落那條線來行動的那一套」。
