I think I have ideas. I could imagine either somebody who's young and edgy and hasn't really made the connection to take reality seriously. I could imagine somebody who has built up enough animosity (due to involvement in the movement or personal bad experiences) to blow past and actively defy calls for civility; you see this play out in radical political discourse. Or, I suppose, a psychopath (which could also be formed by bad experiences).

Psychopathy is mostly genetic and has little to do with “bad experiences”. It can be diagnosed in kids as early as a few weeks of age. These kids will always lack empathy but most are able to avoid being detected as psychopaths by becoming good at pretending to be normal people.

Seems like it's a matter of research still.
