The fact that people with such a cynical and amoral worldview wield so much power not only in US but globally and are willing to wield that power in capricious and petty ways is deeply upsetting.
But what is more horrifying for me is that apparently this administration remains representative of a large section of the US population - with seemingly unshakeable approval by between 40% and 50% of the US adult population according to polls.
I love the US, have friends and family there, have a first cousin in the marines, grandfather born there, etc., and have visited many many times and just find it difficult to reconcile my positive experiences with the place and people with the idea that more than 4 out of 10 US adults could approve of the cruel and vindictive actions of this administration. I'm not being over dramatic by stating that it has genuinely shaken my world-view and belief in the innate goodness of humanity.
