I disagree.I dont think people are born ugly, they are born with genetic potentials post-puberty. There is a first puberty around 13 (that is why 13 is unlucky number.) Then a second puberty around 18.
If you are incel after 13 no hope. If no woman is nice to you at 15 its over. If incel after 18 (due to second puberty) then a slight sliver of hope but not much due to feminism.
