When Trump refuses to peacefully transfer power to his victorious opponent and instead plays "heads I win tails you cheated," that's anti-American.
When Trump sends the FCC chair to suppress speech "we can do this the easy way or the hard way," or yucks it up with the president of El Salvador over suspending Habeas Corpus, that's anti-American.
The "American Experiment" isn't an empty concept, but it is about democracy and law and rights as opposed to conservative cultural values, and when people in power start to argue that the former must be sacrificed for the latter they certainly deserve to be clowned on. Not because they are wrong to imagine an American Ideal, but because they have its contents exactly backwards.
