Trying to engage in good faith here. What did you see in the first few weeks after your 2016 vote that were materially different from how he ran his 2016 campaign (and I mean the hits - "they're sending rapists, ...", "grab her by the pussy", ...)?
I can imagine people souring over lack of follow through on economic promises, or the naked corruption with your $coins, but from a racism/xenophobia/morals perspective, I'd feel like most of the signal was there in the 2016 campaign was it not?
For me personally it was trying to ban travel from whole countries based on race. Morally I didn't expect him to personally be a paragon of virtue. My hope was that the vile parts of his retoric were mostly campaign bluster and "locker room talk", and that he'd defer to experts once in office.
The mask-off racism was just beyond the pale, and lead me to look deeper into his past and how he was starting to govern. It became obvious that he'd mostly cheated or lucked his way into fortune and fame.
