I am sorry to say this is not uncommon with some people, ignorance is what I chalk it up to. In our family there are several members with marriages and children of different race. Skin color says nothing about a persons character and character is what matters. We have dealt with this too. It has even come from a "friend" I have known for 30 years. I have chosen to break ties with this "friend" and write it off to ignorance. Don't let it get to you!
