TIL that his museum says that "Roald Dahl’s racism is undeniable and indelible"
This is the first I've heard of it, but here's one of his infamous quotes:
"There is a trait in the Jewish character that does provoke animosity, maybe it’s a kind of lack of generosity towards non-Jews.
I mean, there’s always a reason why anti-anything crops up anywhere; even a stinker like Hitler didn’t just pick on them for no reason.”
His other quotes tend to be condemnation about specifically Israeli zionism and barbaric murder, but i don't have context as to whether he's referring to palestine or not. Some people might have more sympathy for these statements these days, but a lot of his other quotes have to do with Jews controlling money and media, less defensible prejudice.
"I thought he might say anything. Could have been pro-Arab or pro-Jew. There was no consistent line. He was a man who followed whims, which meant he would blow up in one direction, so to speak."[201] Amelia Foster, director of the Roald Dahl Museum in Great Missenden, says: "This is again an example of how Dahl refused to take anything seriously, even himself. He was very angry at the Israelis."
"Dahl wanted to provoke, as he always provoked at dinner. His publisher was a Jew, his agent was a Jew... and he thought nothing but good things of them. He asked me to be his managing director, and I'm Jewish."
And just as with countless trolls, low-tier comedians, etc., if someone is intentionally being a huge asshole, even if only for the lulz and "it's just a prank bruh/did I trigger you?" of it all, they are still being a huge asshole.
Not to condone it but it was the zeitgeist. There were so many so much worse from that period across all forms of media. His mildly toxic edginess is at least not hidden away.
