Dad's insane takes making me relapse

Decided to come early to my hometown to have some extra time spent with my parents. Me and my father have our differences, but I'm really trying to keep up the good vibes for christmas' sake. All weekend I've listened him spout some crazy shit, here are some examples: "Netanyahu said that it was the egyptians that told the nazis to kill all the jews", "Colonialism is human nature, like the polynesians who colonized the pacific islands". Also dropping the N-word pretty regularily. I've explained to him multiple times how his racism and horrifying takes makes me and my brother uncomfortable, and could he at least try to make an effort to create a comfortable situation for his children so that we could have some kind of a relationship.

I understand my boomer parents who grew up in a 100% white world (I'm in Europe), and accept their inherent levels of racism, what can I do. But he isn't making any effort, he is just trying to make me angry, and he succeeded, and when I loose my shit and we start to yell, he just pretends that he has no idea what I'm talking about and plays dumb and acts surprised that I don't agree with him. He even seems narcisstic. I've given up drinking few years ago, but now I really feel like having a drink, cornered with no escape but the bottle.

Anyone else struggling with family during the holidays?

TL;DR Dad's racist and it breaks my millenial loser heart.
