how to deal with racist in laws

My husband and I are married and are expecting our first baby may 2017. I am black/Native American/English and my husband is black/Irish. Raised by a white father and a mother that is half white and half black. His parents believe That he should be with a white girl- no offense to anyone these are his words. And because he's with me someone who has tan skin his family doesn't really want to be there for he and I as a married couple. They are just there for him. Now they know we are expecting they are cutting him off and it hurts my feelings so much because if my husband could accept me why couldn't you guys? Being on our own isn't the problem it's the fact they are treating us like this because of what I look like.
