My (28M) girlfriend (26F) is obsessed with Nicki Minaj but I think she has been diagnosed with mental illnesses and has some other red flags. How do I gently bring them up to her?

We have been together for 5 months and I am completely falling in love with her but she loves Nicki Minaj way too much. I know that celebrities can all have their flaws but I think Nicki Minaj is a bad person and she doesn't deserve the devotion my girlfriend gives her. <br><br>After doing a lot of research on Nicki Minaj after being forced to listen to her nonstop, I discovered she has been diagnosed with bipolar disorder, borderline personality disorder, schizoaffective disorder, and possibly DID. I also learned she is violent and has threatened people with guns. As much as I don't want to think the worst about the women my girlfriend idolizes, I worry she might not take kindly to me sharing my concerns with her. She'll either get angry, tell me I'm sexist, or she'll say Nicki Minaj is better because she is a black woman. I'm a white male so she'll likely think I'm racist, EVEN THOUGH I'M NOT. I learned of her obsession like 2 weeks ago and before that, she was totally different and never mentioned Nicki Minaj. I try to make her listen to other artists but it does nothing. She goes right back to Nicki Minaj and that's all I ever hear whenever she has her AirPods in. Any advice on what I should do would be greatly appreciated.<br><br>&#x200B;
