A preponderance of religions and philosophies that advocate changing the way one thinks does not mean that most people subscribe to them. Most people are insanely dogmatic including self-described Buddhists (such as those on Myanmar that are cruel to Rohingya), Jews (that abuse Palestinians), Christians (I don't need to describe their flaws), and Muslims. There are tenets of each faith that advocate viewing the world in a more open and relaxed manner. Almost all adherents of these religions and philosophies ignore those parts.
