These folks hunt for a bogeyman that “suits” the ills of their life, then apply the hateful stereotypes.
For the incel example: if they are a failure to launch and also can’t get a girlfriend…
There’s some social order conspiracy + a genetic lottery they lost. It’s not their fault they aren’t desirable, everything was stacked against them. Their enemy (super chads and stupid Stacys) deserve hate because they overlook the incel and keep them down
They never developed social skills, are disrespectful and only see women as sex objects/possessions. If they cultivated some hard work, maturity, and respect for others, they would be much happier with life, and likely find a partner.
The first option is way easier… Just blame everyone else!
