"Gun violence" is of course factually a non-issue in America. Being scared of guns is like being scared of shark attacks or being struck by lightning- technically possible, but realistically such a small risk for the average person that it rounds to 0. But, if you follow certain news or get your social media algorithms tuned to show you certain content, it can seem like this big scary thing.
I also can't really fathom what "repressive moral culture" someone is imagining in America today. There has never been a time of greater tolerance for diverse sexual expression, recreational drug use, religious freedoms or alternative lifestyles. In 2024 you can be a tattooed queer polyamorist pagan who goes to Burning Man for a week and then returns to your corporate finance job on Monday.
But, all the "content for you" algorithms everywhere on the internet will have huge swaths of people afraid of their neighbor and society at large and believing they're under attack and marginalized.
