Honestly, now that you've brought my attention to it, I don't think that 'LTN' should be a serious category of people in general.
I voted no, because by definition, this place is only for incels and incels alone. But where does inceldom end and 'LTNdom' begin? I'd imagine it'd be impossible to draw lines between the two since there are so many distinct variables that influence your overall SMV. It'd just be an endless argument as to what quantifies as what.
Still, I do think that there's a difference between an incel and LTN. A LTN can still get laid, even if it's by an unenthusiastic girl who is only doing it out of neccesity—like an Oofy Doofy who gets to have sex with a girl only after she feels like she needs to have it with him by the 8th time he takes her out and pays for dinner. I'm fairly certain that if you're an incel, you can't even get that. Women are so repulsed by you that they don't even want to give you pity sex.
Still, LTNs may as well be considered 'incel-adjacent,' since a lot of them often end up becoming volcels who haven't figured out that they have to spend an insane amount of money and time to achieve a fraction of what normal guys get. It's probably slightly less, if not equally as miserable as the lives that we follow—well, as long as they don't become a full-blown Oofy Doofy or variety of simp, that is.
