The ideology is problematic.

It's not that they aren't "real". It's the very idea that they are "involuntarily celibate" which is just roundabout way of saying they aren't attractive to anyone.

It's the problem with the extremes of the "you are fine just the way you are and you don't need to change for anyone, just be yourself!" mantra that was drilled into kids for decades. It's true, sort of, but not always true. You don't need to make up some fake identity to "be cool" and come off as some insincere prick. But if your "true self" is an unlovable selfish ass or something like that maybe you do need to do some soul searching and change who you are.

We all know people who are just clueless when it comes to relationships. It's perfectly fine and honestly I respect people who do their own thing and don't care that it makes them less attractive to the opposite sex, but they can't go around and whine about that after the fact. Like it's totally fine by me if you want to be a misogynistic asshole who insults women. I think it's hilariously funny and love watching stupid women get taken down a peg. But if you're a misogynistic asshole who then complains about women not wanting to sleep with you, well no shit Sherlock.
