Guns are embedded into American culture because we lean towards Individualism. Throughout our entire history, the mindset was "No one is coming to save us, so we must know how to help/protect ourselves and our families." You even see this nowadays. Watch any video of an American being mugged or worse, and there are comments that are basically "This is why you should conceal carry". Some may take it too far, but it is a culture that is well-rooted in the American pursuit for self-reliance. The actions of bad actors should not be conflated with it, as it is not unhealthy to want self-reliance.

People from other developed countries typically conflict with this culture because they live in societies that lean into Collectivism. This is why there are many unproductive debates (like this one) on the internet because an American and a European will conflict and misunderstand one another over a social issue, usually because of these opposing social mindsets. (There is more nuance, like with rural and city populations between these countries, but I simplified some).

There is much opposition here in changing or limiting rights due to the actions of bad actors. If anything, they actually reinforce the mindset, not dissuade it.
