Observing from Europe, US politics seems like an extreme case of identifying with the opposite of the enemy. Over several cycles of oversimplifaction, each party simply takes some position from the other, and vocally proclaims the opposite, regardless if there was some truth lost along the way. What's surprising is the tone of the pro-Democrats responses here: vitriolic but without real substance except whataboutism aimed at republicans. HN is the highest quality online agora I know, which to me is hinting that even the upper ranks of US voters are caught in this process.
