Is AUTHOR wrong in the post ? POST : Relevant backstory: 
I am female and I have two younger brothers. Growing up we were kind of poor and our parents also got divorced when we were under 10 years old. Our family life was horrible and everyone hated each other.

Fast forward to our teens, my brothers started bullying and beating me. It really took a toll on me, but nobody in our family listened to me,especially our dad, who told me quit bitching, I am the oldest so I need to figure it out. He also always said that if I didnt annoy them they wouldnt beat me.

Im now in my mid-twenties and even though it was kind of rough for me, Ive managed to build a decent life for myself. I still try to be nice towards my family,though Im too scared to be in touch too much, because I dont think theyre too nice people and they make me feel bad emotionally.

So HERE IS THE ACTUAL STORY;
Yesterday I was chatting with my dad through facebook, because our dog had died. I tried to be nice to him even though I kind of hate him. So i talked to him normally, even got sidetracked and stuff. Anyway, in the end he then said, that he should go and pick up my little brother who lives alone now 

(he moved out at 22 and when we were young they shouted and beat me asking me to move the fuck out since I was 17, i moved out at 19. It was horrible moving out, since I was so scared theyd know where I live. I tried to move as stealthily as i could, but in the end my dad forced himself to get to help me getting my stuff toghe new house, and even though i several times told him not to take my brothers to my house, he fucking took them to my house. Nothing ever happened though, those two psychos never bothered me while i lived there. Oh and they once threatened to rape me when i still lived at 'home')

BACK TO THE STORY
...so my dad says to me my little brother has always been the most sensitive one of us his kids, so he is going to go and pick him up so they can talk. This comment was so goddamn autistic and rude, I thought, and I just replied with what I thought; "What?! Hes not the most sensitive, hes the most spoiled since hes the youngest". And then I just said "but yeah go ahead, talk away". 

Id like to add, that I never got to talk about my problems with my dad. I get emotional and other kinds of support from friends and their parents. But not my own parents.

Tl;dr: My dad said my abusive little brother needs his time more than I do, since my little brother has always been the most sensitive one.
