How or why Scott Adams went completely of the rails is perhaps something we'll sadly never understand. Was this opinions he'd always had, but suppressed, did he somehow become radicalized or was it perhaps medically induced, e.g. a stroke or something. It was incredibly sad to see him throw away his life's work and go down a path most of us at least hadn't foreseen and die having alienated his fans.
Almost everyone is reasonable, it’s the contexts that our reasons are relevant to, which are different.
I think Scott Adams' biggest problem in life (although partially what also made him entertaining), is that he'd kind of pick fights that had little upside for him and a lot of downside.
Some of it goes quite far back, even:

Maybe complain to these guys too, who were apparently still curious 14 years after that blog post?

He could have easily figured this out but didn't, because he preferred to publish this neo-nazi adjacent rhetoric. Nazis use this talking point all the time, you see.
I.e. it's not at all about curiosity. Arguably Scott Adams was one of the least curious famous persons in history. His cartoons were based on office related cliches, and while that provides a bit of laughter and relief to people who have negative experiences from office environments it's not based on curiosity or interest in people.
