It’s always a matter of degrees. The bigger the injustice, the more violence is justified to rectify it. It is in the disproportionality, in my view, where the problem arises.

Never forget that humans are just barely evolved apes. Sometimes a swift knock to the head is required to activate those neural pathways to discourage anti-social behavior. Not always, but also not never. Claiming otherwise is just self-aggrandizing moralization that people use to make themselves sound and feel superior.
