I certainly understand what her overarching point was, and to an extent, I do agree with it. But I really don't think she tried to draw a line between her white fans who care about her message, and white fans who don't. She has no problem throwing all white people who listen to her music into a box together, in my view.
I should note that I've never listened to her music before, and I probably won't, so I'm certainly viewing this as an outsider to the whole situation.
It reminds me of when Kendrick Lamar kicked a white fan, who he invited on stage, off stage because she said the n-word while singing one of his songs. Meanwhile, the Wu-Tang Clan shared a video of a white guy covering Shame On A N****, and they had no issue with him using the word. Not the same situation, of course, but it reminded me of that parallel.
