I don’t know many people who seriously claim that every single atom of American life is racist.
America has no room for nuance, it’s either every police shooting is justified or every shooting isn’t justified. It’s probably not a great way to actually run a country but it makes for great media sales / entertaining politics.
It’s the internet that disposes of context and nuance.
Gone where the long form threaded topics of forums, usenet, etc, replaced with 180 characters quips
It's a lot faster to digest and get a dopamine hit from a <140 char tweet (now <380 chars) than poring over a book, so the outcome of twitter was destined to happen.
