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.
Think of it this way: if you were cancelled and repressed and censored in your own home and unable to express yourself, your efforts to communicate to remain authentic would intensify not die down. Or you die and let yourself morph to the average new censor-ship approved world.
Scott wouldn't do that and neither would I. All this to say I think its normal to intensify your opinions and even take on and be pushed to more extremes when you live in a controversial time of "you're either on my side or the other side and theres no acceptable middle gray area.
