When somebody declares intent to harm you, proportional violence becomes justified as self defence.
If you say you want to hit me on my pinky finger, I’m not justified in killing you. If you declare to kill or eradicate me, as the extreme right does to certain marginalised groups, a lot of different levels of violence are justified, including killing for the really severe cases.
