There's r/foreveralone. I don't know how the community evolved, but like 7 or so years ago it was basically what you described. People seeking comfort over feeling undateable and being scared of never finding anyone, but without the toxicity and hate that incels are known for.
Don't ask me how I know this.
I like to frame it as, even if you can't avoid crashing into a wall, it still makes a huge difference whether you do it with a 120km/h, 70km/h or 20km/h.
