Dahl died in 1990, so you don’t have to worry about supporting him.

Further, he approved removing the insensitive elements of his work, so it’s really hard to imagine that anyone who reads him will turn into a racist.

T. S. Eliot was an antisemite. He was also a great poet, and many Jews admire his poetry.

I don’t think art is the reason racism is still around. The awful state of class mobility in the US is the better explanation for why the ratio of white and black people in poverty has not changed since King’s day.
