Ironically this seems another perfect example of the tribalism the article is about, saying:

- the right-leaning folks were just propagandized - the left-leaning folks were justified

- that questioning this at all is indirectly responsible for breaking every government on earth

- assumed politics must not affect me, or that I must get defensive, run away, or not ask questions

The opposition always being assumed ignorant and the tribe always being justified is a perfect example of tribalism
