Parents are racist

I have a crush on someone and he’s black but I’m white and my mom and her bf is racist towards black people if I go out with them. I want to be able to have him over and them like him. I’ve tried talking to my mom about him and all she has said is that she doesn’t want me to be with him and she’s ok with me being friends with him but not in a relationship. My crush has told me that he has wanted to come over and I told him that he’d obviously have to meet my mom and he said ok when. But I’m nervous that they would try to say something rude I absolutely hate when they are racist towards people and I’ve told them how I have felt and they DON’T listen. My crush has been the most respectful guy I’ve met or have liked. What do I do???? I need some help???

Have any of your parents been racist and if so what have you done?

And I am 15

Please no hate comments I’d just like to have some advice?

He also likes me as well.
