>How is that confusing in the context of everything else I wrote?
Because when you declare a school of thought to be "extreme" it's kind of weird to agree with the core (and most controversial) concepts and only disagree on unspecified details.
On the one hand, it's like declaring that the Catholic Church is run by religious extremists because their wafers are exactly the wrong shade of pale off-white. On the other hand, it's exactly like that as well.
True premise can lead to wrong conclusion.
Some models can work only within a some range.
If you accept only one-handed economists you get into trouble.
