You say that belief in an "obvious fairy tale shows a massive issue with critical thinking and cognitive ability" , but you can't back that up because people who are smart and religious exist.
I agree that believing in something phantasmagorical is a cognitive blind spot. But that's so common criticizing others for it lacks self awareness. It's normal to take some obviously symbolic, illusory, or non-existent things seriously: the law, borders, sovereignty, human rights, authority, hierarchy, language, logic, or math. Are you terrified of those willing to die for human rights?
