nice write up but I'm with @anarcho-andrei on this. words are not violence and sometimes, self defence can be violence on it's own.
Let me give you a quick example.
Here in Nigeria, people believe in what is called Jungle justice. if someone steals from somewhere or rapes a woman and he's caught by the people of the community, he will e severally beaten if not killed before the police gets to the crime scene.
what do you call that? defence or violence?
