Clapton.
Once he was brilliant.
He lost his way with drugs and mental health issues. That racist rant can be, perhaps, forgiven but not forgotten. Not for being in a different context, but because he was screwed up. The worst aspect being that it was a kick in the teeth for all the people whose shoulders he had stood on, and others who were (and some who still are) his friends. It was certainly a nadir for a life that's had some ups and downs.
But I'm willing to believe that wasn't the 'real' Clapton. It was sensibly, if not fully, explored in that recent documentary. I don't think his views were as deeply rooted as, say, Wagner's anti-semitism, but that doesn't stop me appreciating Wagner's music - it does help give it a context. But for Clapton, that rant doesn't seem to make any sense in the context of his life and music.
Ironically when Clapton got his stinky poo back together, he had completely lost his edge, musically, at least as a songwriter.
He can still achieve brilliance as a soloist, but like Mark Knopfler he's wholeheartedly embraced the middle of the musical road for his own output.
And if we are all going to have any chance of living in harmony, we have to remember to 'hate the sin, not the sinner' and accept that people can change and redeem themselves {all said in a religion-neutral way].
