How do I have a conversation with my father?

My (23F) father (58M) decided to start saying racist things to me three weeks ago. It really came out of the blue. He told me he wasn't racist then made a demeaning and offensive statement about black people. I wait for him to do/say something racist again to call him out and let him know he can't make these statements but now he is telling me I'm trying to attack him.<br><br>I know I'm going to have an argument with him but I don't want to be confrontational. I just want to have a conversation with him but I am afraid that will cause him to make an ultimatum to me: "If you are on the side of (group) instead of me, then you should leave."<br><br>My father is a control freak and a narcissist who has been emotionally and verbally abusive to me since I was a child. I have a hard time talking to him without it escalating. He has no accountability or remorse for his behavior and will use gaslighting and manipulation to get me to carry his narrative.<br><br>What should I say and do to have this conversation without it becoming a shouting match?<br><br>Edit: He's not a Trump supporter but radicalized on Twitter over the past two years. I think he's going down rabbit holes and falling for misinformation and becoming radicalized. He has never made these statements before but has always been radical in his politics. He has never been remotely racist but has a history of making radical statements against some groups of people.
