Incredibly well-said.
I would just add that, you do need to sweat the small stuff.
I've seen a number of people claim that a problem with "the left" is that they get upset about every single "little" thing Trump does and that they should just ignore the "small stuff" and only worry about the big problems. Demolish the White House for a ballroom? Insignificant. Put his name on everything? Small potatoes. Pardon thousands of convicted criminals, including some millionaire and billionaire donors? Doesn't matter. Accept a $500M bribe in the form of a luxury airplane? Who cares.
The problem is that grift, corruption, autocrats, and authoritarians always start small. They push the limits of norms and convention, then the edges of the law, then "small laws" that don't meet the criteria for "high crimes". A broken constitution and subverted free society is built on the bones of the "small stuff". If you wait to fight back until the big critically dangerous stuff is happening, you've waited too late and have already lost the farm.
Slippery slope may be a logical fallacy but it's modus operandi of people like Putin, Trump, and yes, Hitler.
