advice on racism in a relationship

I don't condone racism. Me & the baby father is not together. my baby father is mixed white mom, black dad. It's seems like the women in his family LOVE black men (they all have mixed children) but never approve of black women that the men in their family date. It ruins their relationship & it ruined ours. He's always on his mom side no matter how wrong she is & vise versa! On my baby shower day I want it to be about nothing but the joy of this baby girl being in my tummy, it's my first child. I want to invite her dad side of the family because it's her family but they're all super fake to me & I know it'll piss me off but I feel like if I don't invite them it'll cause a bigger situation, & that's not what I wanna do. I want this shower to be perfect! I don't even want to invite the father because he says such stupid things that'll kill my vibe. Should I just invite them or should I go with planning my perfect shower?
