I'm gonna be honest I really don't trust anyone who hand waves online harassment off as "silly online drama", because online harassment is deeply fucking traumatising for the victims of it, but to the wide majority of people it's "not a big deal" and "this kinda stuff doesn't matter in the real world", all I can ask is did you motherfuckers not listen during online harassment psa's in school???
And like. When your entire social circle exists online, you can't just log off. The weirder someone is in wider culture, the more likely they are to have a heavy or exclusively online social circle. The people targeting folks online know this, and that's exactly why they put in such efforts to poison people's social connections. If you can get even one person in someone's social circle to distrust them, it spreads stupid easily unless there are active efforts to cut off that kind of movement.
These people want to kill us, and they're using the fact that we're not getting wider social support offline as one of the primary ways of doing so. Anyone who says "just log off" simply is ignoring the modern reality of how people socialize.
