Yes, there are many jurisdictions in the US with unconstitutional arms laws.
But even then we don't have an attitude that self-defense is categorically "incompatible with society". Many politicians, activists, wealthy donors, and voters are de facto opposed to self-defense but they at least have to pay lip service to it.

Unless you consider hiring (or working with tax-payer funded) armed protection a form of self-defense. Then they're very pro-self-defense. "Gun control" in America is a euphemism for "gun consolidation". We don't believe weapons of war belong in middle/lower-class people's homes, but they sure as hell belong in every patrol car and on the streets of countries whose oil we want to control.
In my entire (very southern, very conservative) state, until recently, a knife designed for offensive or defensive purposes was illegal to carry.
Offensive or defensive wasn't clearly defined, and it was pretty much just interpreted as any knife you intended to use for offense or defense.
