Yes. This is that "bigger picture" aspect I was referring to earlier. De-escalation is usually one of the best options (where available), but there are times it isn't.It depends where you are. If you are socially locked in. School for example constantly backing down may create more issues in the future.
If you are never going to see the guy again. Then who cares.
But if they are going to be a continued threat you may have to show some teeth.
Otherwise for me. If i am confident i can wreck the guy. I don't care if i back down. But if i am less confident I may have to be more aggressive.
By the way this is why we can't really have self defence conversations. Because instead of certain concepts like deescalation is a tool that works for me in this sort of situation. We get you should always deescalate. Cos self defence.
