How do you handle being around family/parent who’s basically racist ? When you are mixed race

I’m having to try to handle this. Hearing about how my white parent hates immigration so much, seeing them stare at nonwhites in public, it just makes me feel like they regret having me with my black parent. They were a liberal before and against trump and were for immigrants now since COVID it’s a 180 and they’re basically giving racist teas. They used to always talk about how republicans and whoever are racist. Now if I even bring up the word “racist” they become really quiet.

It’s clear to me that my white parent has become a racist.
