Remember with all these hate crimes against Asians, including using deadly force, going on, in the US the same level of response in return can be a legal excuse. So if you think because your life is being threaten by anyone coming up to you because you see it happening in the news, you can respond with the "same" force even though they might not have that intent. You don't know but you don't have to know their intent. So if they throw just a punch at you, using force against them, including deadly, can be legitimate depending on the circumstances. They're looking to do harm against you and if you feel that's happening, that's all that matters. You're fighting for your life and if you end up killing your attacker in defense that can be in the name of self-defense.
My family and friends that are Asian always tell me of racist incidents they encounter and I think in my head, "Why doesn't that happen to me?" I don't encounter many direct incidents of racism and I can only think it's because of attitude. I'm going to do something back including violence if that's what someone is bringing to me. Chinese/Asians are taught to do nothing when confronted. And people can smell it on you. It even happens in international affairs. Everything the US does against China like openly saying they want to destroy China's economy because they can't beat Chinese competition... if the Chinese were opening saying that of the US, to them that's essential a declaration of war and they would immediately respond in kind. China does nothing in response except maybe some words. That teaches people to keep doing it and not how naïve some Asians are in thinking do nothing and nothing will happen to you.
For me I have to be careful with the kind of force I can use against an attacker under the law but for elderly Asians that you see on the news being beaten and even killed by young strong men... using deadly force on them like even using a gun, there's not going to be much sympathy for the attackers even if they die.
