Well, he really is the most widely-known and mainstream singer who made a dangerous, criminal image part of his mystique. There really aren’t many other examples to use. But the point still stands.
No. It still has historic value and even if it didn’t I’m not much for censorship. I just strongly disagree that the song isn’t racist and I don’t see any need to pardon the singers for their contribution to the casual racism of their time period.
