top level summary: manosphere edgelords are fucking losers. when they feel emasculated they target their violence at who they hate (usually women, school teachers are often women), who they're jealous of (in the case of school children, school children are often representative of the last time the terrorist felt whole, when they felt safe from the world, and before the pressure to perform masculinity became overwhelming during puberty. additionally children are representative of a community's hope for a future, and shooters are often completely doomeristic in their worldview), and who they feel does not present a threat of fighting back, or "soft targets" as they're sometimes called (school shooters are very consistently trying to crack a high score. they make references to prior shooters and keep track of a leaderboard in their diaries and notes)
