I mean, we're mostly just talking about Dawkins, right? And I guess we can include Cleese and Gilliam, if we stretch it, but the Pythons who Adams was closest to were Graham Chapman, who died in the '80s, and Terry Jones, who seemed like a pretty good guy AFAICT.
Adams had a lot of friends who seem like they're still pretty decent people. Neil Gaiman seems like a good guy. I haven't heard anything bad about David Gilmour, and the most controversial thing I've heard about Stephen Fry is that he's
still narrating audiobooks for JK Rowling, which isn't great but doesn't put him on the same footing as Dawkins, either. I was gonna say that the only reason I have to suspect anything wrong with Lalla Ward is that she's married to Dawkins, but I looked it up and they've been separated since 2016.
Douglas's daughter Polly seems pretty cool too.
I dunno, and we'll never know; maybe Sandifer's right and Adams would have gone down the same path as Dawkins. But I don't think it's fair to the man to make assumptions about what he would have said and done if he'd lived. He had some friends who turned out to be pretty awful, but he also had some friends who seem like they're pretty okay. His humor always seemed to me to come from a place of compassion for human foibles, even when he showed disgust and contempt for the horrible, stupid things we do to each other and our world.
