Sorry but to me it’s a different league.
Clapton urged the audience at a gig to “get the foreigners out and keep Britain White” If that’s not inciting racial violence I don’t know what is.
This was probably at the height of his career and a lot of bands and artists would have refused to be on the same bill as him at that time-he was the catalyst for the formation of Rock Against Racism. I don’t think the festival would have touched him at that time.
Even if it was a result of his addictions he said in his autobiography when talking about it that he had learned to keep his ideas to himself.
