"Gun culture" and "kids committing crimes" are two separate things. "Gun culture" (if you can even call it that) is IDPA, USPSA, Cowboy Action, skeet (haha), trap, hunting, historical collections, non-historical collections, and defense. Not murdering unarmed kids in a school with a stolen or illegally purchased gun. Incel culture maybe but not "gun culture."
This is like saying "car culture" is running over grandmas while drunk driving, rather than cosmetic/performance mods, racing, antique car shows full of Chevy Bel-Airs and Novas, muscle cars, etc. It's not. "Alcoholic culture" maybe but not "car culture."
Maybe you should take that step back.
