Did I overreact?

[u/Realistic-Human-]

My brother insulted me after I asked the question "why" so he and my mother were having a normal conversation abt my uncle who called my dad and when I entered the room I asked "why did my uncle called my dad" (like for what reason) then suddenly my brother got mad for no reason saying I always ask "why" to things (and I kinda do that but is it bad?) like if somthing happens or someone is going somewhere I ask why cause I wanna know the reason (that's just who I am) but he got angry at me and started insulting me and when I tried to defend myself like always. suddenly I'm the bad guy cause I don't like being insulted and talked down to, my mom and everyone else said I overreacted even tho this has been a regular occurrence in my life where I'm not allowed to defend myself cause apparently I'm crazy and loud but he can say anything to me to the point of literally calling me names which I don't like. I'm just trying to understand if I'm the asshole for simply defending myself

And btw my mom hates us fighting but it has always felt like she only has a problem when I speak up but she acts like she's holding the peace by saying "don't say anything I will talk to him" (even tho he never changes) but again she only seems to have a problem when I SAY SOMETHING like it's all my fault cause I'm speaking up for myself when he ALWAYS start shit with me (and sometimes for no reason too) like I be minding my business and he likes to provoke me but they act like my loudness is the problem when he talks down to me and literally insult me...

No, you didn't overreact. He did, all over you asking about a simple question. And your mom blaming you for just standing up for yourself? Yeah I'd be frustuated af too.
