FWIW my OP here asking about the female response to the same sorts of pressures that have resulted in the incel movement in males, was provoked by this show.
Katie, the murdered girl, had been humiliated in an attempt to win over a boy she thought she liked. The boy she wanted rejected her. Social media was an impact on her, likely part of her decision to sext and the means of her social degradation with her body being shamed. She turned to bullying someone else beneath her in response, using incel ideology as a means of attack, ironically pushing a lower social strata boy further into the incel mindset, as much as he still denied such even to himself.
There are similarities there in the mindsets. The manifestations in responses different. The boy resorted to physical violence in his attack back at a representative of the other gender, the girl with cyber bullying that got her likes.
Which made me wonder how those similarities and differences which begin in childhood play out into adulthood as well.
