Idk I’m a married dude nearing 40 who is on dating sites a fair amount (it’s cool so is my wife), and I’m a pretty average guy all-around, and it doesn’t seem like this hellscape you paint it as. I have everything possible stacked against me for online dating, and I consistently get what I’m looking for.
Yeah there are lots of crazies, but that’s because crazy people exist, and you’d run into them in more traditional dating too. Check out any romcom from the 90s and there’ll likely be a montage of crazies.
