You should be able to use reasonable force. If you’re trying to subdue a homicidal maniac then you can choke them unconscious or knock them unconscious or kill them if that’s all you have means to do. But if you just have someone who wants to be rude and yell in your face, then you don’t have a right to kill them.
I think it depends on who causes the confrontation and who is escalating the situation to different levels of violence.
Also, I think there’s different ways to interpret stand your ground as a concept. You can stand your ground and use reasonable force to secure your safety. You should not be able to stand your ground and murder someone so as not to inconvenience yourself if you don’t want to take a step back or move out of someone’s way for example.
