My bf’s (22M) mom is passive aggressive towards me (24F)

TL;DR I 24F am concerned about my relationship with my 22M boyfriend’s mother, who makes stereotypical racist remarks and sometimes talks to me like a child. Despite the mother’s outward niceness, including cooking for me and inviting me over, I feel uncomfortable due to the mother’s comments about me being biracial. I have expressed my concerns to my bf, who has been hesitant to address the issue with his mother. I am unsure if the mother genuinely likes me or has an issue with my racial background.

My bf 22M and I 24F have been together for 9 months and it has been amazing. I can see myself marrying him one day. The only problem I could see us having is me not getting along with his mom. She is nice to me for the most part. She cooks and invites me over to eat, she lets me stay the night with him in her house, and she invites me places. She even said she sees me as her daughter now the other day. The problem I have with her is that she makes stereotypical racist remarks and also talks to me like a child sometimes. I am biracial (black & white) and my bf and his mom are Puerto Rican. She has said seriously that “Indians stink”, “she would never let her sons date an Indian women”, and she “avoids a certain Costco because there’s too many Asians and Indians in there.” I don’t care that I’m mixed, racial remarks about anyone is offensive to me. She also has said “no offense, but black people pop out babies like no other.” “The mall got robbed and it was a group of BLACK people who did it.” “Black men come with a lot of baggage.” “No offense, but do black people not like the outdoors?” She has said all of this knowing I’m half black and has said it in front of my bf. I told him how it bothered me and he replied with “idk what to do.” I told him to say something when she says stuff like that and he said he would but hasn’t. It’s like he is afraid to speak up to her. She also let me stay there for a week and added me and my bf to a gc where she said “Hello, if I get mad at you, I'll be the bad one. I left a few dishes out to dry, and you couldn't put them in the cabinet. Im serious 😒 when I said I couldn’t deal with it.” But she never told us to put the dishes away and I’m unaware of how she wants the house run because I don’t live there! She also pointed out a box of drinks I like at Costco and was in front of the flavor I wanted, so I was patiently waiting for her to move. She then said “baby you have to pick up the box and put it in the cart yourself!” aggressively and sarcastically. My bf, her, and I were checking out, and we had a routine going. I handed her the stuff, she scanned it, and my bf bagged it. My bf walked away to get something, and she looked at me with a fake smile and asked “do you know how to do this?” (Talking about scanning the item) sarcastically like I’ve never done self checkout before…. So I am confused on if she actually likes me and does she have something against me being half black? What do you all think?
