Back when I was a climate change denier (90s) we denied the climate was changing. There was a rather seminal point where a prominent study to show that the climate wasn't warming actually showed that it was and that team had the intellectual honestly to admit their hypothesis was wrong. Some of us, including them, shifted to accepting climate change as an issue. The dogmatic ones switched their stance to admitting that yes the climate is changing, but we can't prove it's caused by humans. That's where they sit now, and the Breitbart article was relatively consistent on that. They just fell down when it came to the actual papers they cited.
The cigarette companies went through a similar shifting denial phase, I'm hoping that we all reach a science based acceptance on this too. Key to that is understanding how people like soes think, and I feel like I understand where he's coming from better now, so I'll count that a win for my own growth.
