I haven't read a ton of Dahl's work as a adult but I have been going through the Lovecraft collection and the racism is sort of baked into the work. I'm not saying throw it out if anything the only thing positive I can say is Lovecraft work probably wouldn't have worked so well if it wasn't his idiotic racist views since in a way a ton of his work is based on fearing the outsider and basically is racism in a super hyperbolic way. I do however agree mostly with your other point that the big problem is supporting currently alive creators since consumption does sort of benefit them allowing them to push their views in the real world.
