With all due respect to your experience and with sincerity, I must ask: did you miss Trump's first presidency? Surely that was the time to become disillusioned with the USA, if not before?
Speaking from my own experience... I was hoping Trump was an anomaly. That the US would have the good sense of NOT voting the guy that directly tried to subvert the electoral process. That somehow the American public still had a moral compass and that the many Americans I admired were representative for their country. I was obviously a fool.
Otherwise, I kept saying to anyone who had ears around me what a grave danger Trump is. I've been doing this for more than 10 years. I saw him as a corrupt asshole since reading his book "The art of the deal" more than 20 years ago. He came highly recommended in the sphere of the then emerging "manosphere"/ PUA culture of the 2000's (I cringe at my own stupidity and shallowness now).
