It could just be a collection of volcels as reddit posts like that do not really prove it. If you had one of them join a dating discord and try and act cute I'm positive they could get into a relationship with someone. There are plenty of people who are desperate for even a tiny bit of female attention.
It is wild that people who probably consider themselves to not be sexist will insist that women are somehow magical fairy princesses who couldn't possibly be negative toward the other gender over dating matters.
Just look over the comments in this discussion - it's full of people insulting men.
I don’t think FDS invalidates my point. Misandrists are real, so are misogynists, incels are real and so are femcels. My comment was giving a resource for femcels.
