It's strange because we also have an extreme culture of litigation, and so much as an unwelcome or aggressive touch (without injury) could technically support a civil lawsuit or criminal charges for assault/battery.

The difference is that we apply justice differently depending on your political belief, so the acceptable violence is usually one-directional. Any violence by left protestors will be treated akin to terrorism. If you're a right wing crazy harassing people protesting for a left cause, police will look the other way and you may not even be convicted for murder (e.g., Rittenhouse). Worse, the police are usually the ones being irrationally violent - like the George Floyd protests in which nonviolent civil protest was suppressed with military-level equipment, tactics and violence.

It’s because we have a lot of repressed rage because we know deep down we really are one of the shittiest countries, despite what all the cousin-humping country singers keep caterwauling about.

Cognitive dissonance is a hell of a drug.

I remember visiting another country as an American high-school student. We were shocked and overjoyed that BOOBIES could be shown on network television. It's insane some of the violence that's totally fine to show, but definitely not a woman's nipple!
