Good God, do these people (incels) ever actually listen to themselves? Whining and bitching, let alone wanting to commit mass murder, because they can't get laid? How is that remotely "manly," even by the most old-fashioned and rigid expectations of masculinity?
Of course Cosby never, ever would have had trouble finding women to have sex (casual or otherwise) with him. His reasons for drugging his victims were either due to a sick fetish he has for limp, unresponsive victims or because he hoped (evidently with reason) that drugging the women with whom he cheated on his wife, would prevent their coming forward and exposing his wholesome, all-American family man image for the lie it was.
