"... the former Ambassador to the United Nations and a fellow at AEI (and subsequently National Security Advisor to President Trump). Bolton, my friend insisted, was a loathsome, hateful, racist, neo-conservative warmonger. The list went on and on until eventually she said that he looked like a walrus with a moustache. You could tell by his physiognomy, she explained, that he was a psychopath. 'But what about the policies?' I responded, trying to redirect the conversation away from personalities. The more she spoke, the more I recognised her broad disposition as something I had experienced earlier in my life. Her attitude was almost entirely tribal. Two things, in particular, stood out: an almost blind hatred of a particular group (Republicans); and secondly, the use of deeply personal attacks on individual researchers to justify that hatred."
From "Tribalism has come to the West/Hostile and polarised, today's America reminds me of my Somalian clan" by Ayaan Hirsi Ali (who worked at AEI at the time of that conversation).
