I'm sure next year will be worse.
I don't see it getting better. I think draconian gun control stuff would help a lot (and at this point, i'm firmly in the draconian gun control camp), but it's hard to ignore that there's a serious problem with young men in the US. Just a lot of amoral rage that apparently enough people fantasize about and actually carry out. Either "for the memes" (which I think is the root for most of these) or some dipshit cultural purpose (which I think a lot of the "for the memes" types latch onto because of shock value).
Whatever it is, I do think that these weirdo online corners of the internet like 4chan that a lot of incels and otherwise perpetually online, lonely young men flock to are a tinderbox. And when guns are super easy to get, these guys can explode. That (insanely easy access to weapons) I think is the key ingredient to the America problem. Though, (for whatever reason), I don't think that's the only ingredient. I think there's something else going on with a lot of American young men that (for whatever reason) isn't going on in a lot of other western countries. Have no real clue what it is though.
It just seems like in the last decade, there's been a lot of young men in the US eager to take others with them when they decide they want to kill themselves. Obviously removing guns (i.e. making them much harder to obtain) from that equation helps (and we should do it), but I don't think it totally solves that problem, which, imo is a relatively new phenomenon.
