i never said that they arent allowed to react or something if they know one is coming towards them
I never said that you said that, I'm saying they should be (in your standards) "overreacting" because of the devastation it creates. Your little brother should be worried, unlike you he cares about himself and other people and he also doesn't want them getting injured, or even killed.
Seriously, that thing in between your ears is there for a reason.
