I'm genuinely curious about this worldview, because I personally cannot empathize with this. It's abhorrent to me and my values.
If you walk out your door start groping people or try to run off someone's child, you will encounter violence pretty fast.
You couldnt make a post on HN if it werent for violence, or the threat of it. you have a computer to type on because if someone were to take it, they would risk beating or death. someone built the computer because threat of violence makes them work for a living instead of taking what they want. sometimes you can be minding your own business at a desert rave and violence comes for you anyways.
im saying all order, justice, and authority is based on violence. the only difference between an extrajudicial vigilante and a sanctioned enforcer, is that the enforcer is on the side generally considered more threating.
If you are sufficiently transgressive, violence is always a possible consequence, for children and adults. it is a simple fact of life.
Also we let/cause lots of things to happen to animals that would likely need therapy if they were humans, so this comparison really doesn't work.
Does every dog / chimp / giraffe that got nipped by mom for being a brat need therapy?
