Mixed Boyfriend Shifting Between Identities?

I'm using a throwaway account bc I have no idea who to talk to regarding this situation.

I (26F) have been with my boyfriend (29M) for 6 years and we started our relationship with a sense of shared identity. They're mixed and I'm black, but they introduced themself as identifying more with their black side, and it was a healing experience that we built a connection on. I would still have wanted to build a connection with him even if he identified more as white, so that wasn't an issue to me. I've dated men from different backgrounds before. I saw him as my twin flame, physically, mentally, emotionally starstruck by him.

6 years later, now that he's making money, he has been going hard saying white people are the most oppressed group, black people more likely than not are criminals and are poor and don't contribute to society and white people are made to feel ashamed of being white and he's not going to raise our future kids to be ignorant of that truth. Otherwise, he said I should date a black man. I have always been an I care more about your individuality and personality than your racial background kind of person, so him saying these things was immensely painful. Saying things like stereotypes exist for a reason and white people are bullied for being white more than any other race. He wants me to be more supportive of exploring his white side/cultural background, but in this context, I can't. He says he's race-neutral and that if white people were doing something wrong or racist he'd call it out too, but I've never seen him be this critical of whiteness or white identity before.

I have tried to stress that hating white people is a bad thing, yes, but stereotyping people isn't any more helpful. And I have tried to introduce a more middle-of-the-road approach considering multiple perspectives, but he's only considering the most radically white pride one. And I've been feeling resentful about it. He said that he pretended to act more black when we first met because he didn't think I would l like him if he leaned towards being more white, and now that he's making more money, he thinks it was just a phase and doesn't care about aligning with that side of him. And I'm impeding his desire to fully express himself. Because this obviously really hurts me.

I don't think I could be with anyone who thinks like this, but I'm struggling to understand if this is another "phase" because he has no idea how to integrate all aspects of his identity, but its painful. There's been multiple arguments that have led up to this, but I don't know what to do. I love him, but I'm starting to wonder if love isn't enough.
