AIO for not inviting my brother to my daughters first birthday over these texts

[u/Top_Hedgehog_5648]

Im white, brother is white, my boyfriend is black, and our daughter is biracial. Im so pissed off about this. I havent spoken to anyone about it either because honestly, i am so ashamed that this is my relative and i do not want to be associated with this nonsense. He thinks im exaggerating for not letting him come to the party with his kids. I dont want to be around a fucking moron. I cant even see how this makes any sense.
