In almost all cases the isolated and abused trucels either don't have the tenacity to sign up to spaces so openly misogynistic, or they interact sparingly, or almost invariably become a lolcow. Tabula Rasa had highlighted an interesting study on social defeat in mice quite recently, and I think it is apt - if someone is truly horrifically ugly and abused would they develop a desire to broadcast their presence and hatred or suppress it? The 'Incels' that inevitably end up flamboyantly dishing out wanton misogyny are almost always the ones who have some purchase of power over people in reality, and so the cabal of 'venomous and borderline-inclined failed normies' is not nearly as catchy as 'trucel pariah', but that's what the demographics tend to be, alongside a hefty dose of government psyop and brainiacs poking their nose in to study spiteful mutants.
