AITA found my boyfriends burner Twitter account

So basically what the title says. And I found so many misogynistic things that he post about. I already told him that I found the burner Twitter account (which he didn’t like AT ALL and was pissed about it for a little bit). He’s not hiding anything he just knew I wouldn’t like the things that he way saying on there. The things that piss me off the most was saying stuff like “I know it’s stinky”, “let me sniff it”, and weird things about women vaginal areas. I don’t know how to bring this to his attention, because I know he’ll be mad about this conversation topic again.
