@dga471 It seems your post ignores the dynamic I quoted below with many of its examples. I don’t see many of those examples acting exactly in this manner - especially when it comes to the examples of Reformers adopting Roman Catholic thought (both are based on the Bible) and the modern creationist movement coming from Price (the ideas are based on creationism).
I’m not seeing refinement on “both sides” in any of those examples. Maybe I’m missing what you see or misunderstanding this concept.
