There’s an elephant in the room you’re not talking about. Nobody’s talking about it. Of the roughly 30,000 gun deaths per year in the USA, around 20,000 of those are suicides, and 7/8ths of those gun suicides are men. That number is staggeringly larger than the mass killings number, yet when a mass shooting occurs, the media rushes to blame men.
I think there may be something we can learn about the overall problem purely from looking at the media’s behavior. The “gun deaths” problem is, mathematically speaking, a men’s health problem. Nobody covers it. The feminists aren’t going to march on Washington for men’s health because it would undo their privilege narrative, and the men aren’t going to march on Washington because they’d look like pussies. At a very base level, women don’t care about men, and men don’t care about men, and that’s mirrored in the media. And that lack of care, at a societal level, may in fact feed these extremely rare mass shooter incidents as well.
