I didn’t know that about Jules Verne. Thanks, akuperma. I knew Roald Dahl was an anti-Semite. But I know people who like his books anyway.
The truth is that there are a lot of bad people who have produced a lot of beloved artworks. I think that the OP was focusing on the content of the artworks.
And it’s not like buying a copy of “Around the World in 80 Days” is gonna result in a contribution being made to the Moslem Brotherhood or something. Verne is dead and gone these many long years.
