How to confront my boyfriends rude racist parents

My boyfriends dad is a drug dealer and his mom is a felon and I try not to hold it against them but I feel attacked I am constantly judged because of how I grew up I love my boyfriend with all my heart and I love his parents. When me and my boyfriend first started dating five years ago I never mentioned anything about my parents because we are well off . This is not me bragging but I wanted to give a good background My father built his own business and is a millionaire and my mother plays tennis and does triathlons we do not live extravagantly because my father does not see the point in it, I constantly work for what I want and am not handed it and I like it that way . but They constantly are making comments about how I am too spoiled and always say things about how much my dad makes and how my mom is a housewife . It has come to the point that they are now making remarks about my race because he is black and I am mixed . My mother is Hispanic and my father is white and that have constantly said

“if you were fully white you wouldn’t be welcome in this house”

“Your lucky your half Mexican or you would not be with him”

“Do you think your dad would be interested in buying coke from me , I hear white people do that “

My boyfriend has had many talks with them but nothing is changing
