What the hell even is that? You're either born ugly or you're not. It's an ignorant attempt at associating men's retribution towards women's bullshit as "basement-dwelling."
An involuntary celibate (INCEL) gets no pussy, because he's ugly/physically undesirable. Naturally, he might gravitate towards blackpill ideology or remain bluepilled and unaware of female nature.
Blackpill basically teaches them that women are and have always been materialistic and selfish, choosing the best men to breed with. You don't need to be an incel to know that.
Some fucking celibacy is actually a good thing
Tacitus wrote how Germans preserved themselves for marriage and punished "early sex" with either banishment or exile (this applied to men as well)
Meanwhile Rome was a bastion of depravity because slavery, you want some pussy? Just head to the slave market and take your pick
Whoredom was also rampant (was sold openly near arenas and chariot racing stadiums) it literally required the govt to intervene and force women to become mothers
Not because they cared about *le hecking trad values*, but because they needed more men for their wars of conquest
