Why does my semi-conservative mom listen to Doja Cat, but not Morgan Wallen?

My mom, who is strongly anti-Biden, supports some aspects of both Trump (especially the Tucker Carlson kind of Trump fanbase) and Jill Stein. She's generally anti-political correctness, but she is a strongly spiritual person and when I told her about the iced teas sold under Morgan Wallen's "Ryl" brand, she questioned my obsession with Morgan Wallen. I told her the whole story, and she accepted some of my reasons, but when I brought up the n-word part, she said that he can't be saying it because "he doesn't have the black card." My mom typically listens to Doja Cat, but sometimes also to Kanye West.
