How do I shut down my best friend’s sexist boyfriend politely?

So my best friend is dating a guy who’s a misogynist. I absolutely hate his views about women, but my best friend usually ignores his opinions because she’s a very chill person. She told me she’ll handle it in her own way. I did advise her to confront him, though.

Whenever I see him, he starts huge debates about whether women should drive because “they cause accidents,” how women are “too emotional,” how they should be gentle, and whether a husband should “allow” his wife to work or not.

At this point, I genuinely don’t know if he has some itch to convince me that his ideology is right. How do I tell someone to stfu in the nicest way possible
