I don't really identify with any particular movement, but it's important to note that there are plenty of people who legitimately oppose the core concept of rationalism, the idea that reason should be held above other approaches to knowledge, this being put aside from other criticisms leveled at the group of people that call themselves rationalists. Apparently, rationalism isn't obviously correct. Unfortunately, I don't really have enough of a background in philosophy to really understand how this follows, but looking at how the world actually works, I don't struggle to believe that most people (certainly many decision makers) don't actually regard rationality as highly as other things, like tradition.
