Inceltears/Bluepill generalizes women more than incels do
Incels say that here's this Gaussian distribution and women's behavior tend to fall within this distribution. Sometimes their behavior is what would be considered "shitty" depending on your own beliefs.
Whereas IT and bluepill generalizes that all women are wonderful and can do no wrong. They are the ones who think of women as a hivemind. In their view, women can never be the asshole. It's impossible that a woman has ever harmed an incel because women are perfect angels. The woman must have had the good personality and the incel must have had the bad personality ALWAYS.
