in no small part "thanks" to social media, no? like yeah in the us and anglosphere it's no small part car centricity, but like the blog post points out, this is a trend that's visible even places that don't have school shootings and car centricity, so it kind of has to be social media. (actually proving it is hard but, like, at this point, i don't see how it can even be disputed by any reasonable person, only pedants)
