Yes. This is a "Very Online taxonomy". While I think it's useful to think about mechanisms of collapse, the author seems to have a clear bias towards the belief that collapse will happen which feels very non-objective. In my experience, the vast majority of people I interact with (maybe 90%+) fall into the author's categorization of "radical denier" or "partial denier". I don't think there's anything "radical" about the belief that while things will change, society will go on. But calling the belief radical and suggesting that this is a belief only shared by Very Evil People (e.g. Koch Brothers) is a disingenuous straw man. For the record, if I had to put myself into this unscientific taxonomy, I might be somewhere between a technological and economic optimist.
