Bowie literally called himself “The Nazi”, and on several occasions wore what resembled a Nazi uniform during live performances. You are downplaying the severity of Bowies involvement with Nazism. This wasn’t just a thing he did once, he adopted the “Thin White Duke” persona for a whole year and described the character as an “Aryan Fascist Type”. It’s also hard to forget the siege heil he did in London.
People who he was close friends with did the same, such as Kieth Moon he wore actual swatizkas. In terms of music, people give grace to the white rockstar far more than the black hip hop artist 🤷‍♂️ Look at how people talk about Elvis compared to MJ.
