Trick-or-Treating with friend whose parents are racist?

My daughter is 13 y.o. and white. One of her friends is the same age and Indian. My daughter told me that her friend's parents are racist towards white people and that this girl's parents won't let my daughter come over to their house to go trick or treating with her friend. Another friend will be joining them for trick or treating starting at the other girl's house and because this other girl is black, she'll be allowed to go inside their house. My daughter plans to meet both friends on some street corner in the Indian girl's neighborhood where they can trick or treat together and then I'll have to pick my daughter up later from the same street corner. This sounds so bizarre to me! I don't know how to handle this. I want my daughter to have fun trick or treating with her friends but I don't want to give in to the parents BS racist nonsense. Advice? Thanks for listening.
