Normies already intrinsically know the black pill is true.
At least the Chads do anyway ie the men.
It is their job however to keep the rest of the men out there from ever waking up to the truth and reality of women as the average guys or guys with some potential then can know what to do in order to compete with Chad for all the prime pussy and guys like us tend to stop simping/cucking/white knighting for women which means going out of our way to be nice to them and or helping them in some way because we know we're not going to get anything out of our "good guy" behavior anyway due to realizing it was already over for us the moment we were born due to whatever genetic defect/s.
So Chad doesn't want men across the board to be blackpilled as it only creates headaches for him of increased competition and not as many men coddling and protecting his "queen" or rather "harem" from danger and or the female's own stupidity, etc, etc.
As for the Stacies that for whatever reason are intelligent/aware enough to intriniscally know that the black pill is true or who figure it out due to higher IQ or smarts than other Stacies they don't want the black pill to be widely available knowledge for their own selfish reasons ie not wanting lesser men to be able to work hard and PUA max and thus have the chance to ascend with them that way (instead of a genuine natural born Chad) and they of course want guys like us to keep on simping/cucking/white knighting for them as that helps them rather than in their minds "harms" them which is what of course happens when we find out black pill truths ie we begin correctly slut shaming them and or simply avoiding and not helping them.
