Upset and frustrated

I come from an all white family, I mean, even the family friends are white. I’m pregnant with a biracial baby.

My bio dad’s family are all very racist but I have zero contact with them.

I didn’t think anyone else in my family was racist but yesterday, I told my parents I was having a boy, and my stepdad was disappointed. He hoped I would have a girl so my child at least wouldn’t grow up to be a black man. And then my mom said “oh, I didn’t even think about that.”

I couldn’t even formulate a response, just went home. I didn’t tell my SO what they said because they seem to genuinely get along with him so I didn’t want to upset him.

I’m just so angry right now. I love my parents, but I won’t accept them treating my biracial children different than my white children. I think I’m just going to slowly “drift apart” from them.
