@OutOfExile_IDR_Voice@paul@disability@disabilityjustice@MadMovementMastodon I read it as an adjective rather than a noun: referring to a person who is simultaneously a criminal and mentally ill and a drug addict and a wife abuser. It reads to me like it's meant to be a list of risk factors for violence.
Who has what disabilities is irrelevant.
The ableist part is using mental illness as shorthand for predisposed to violence.
