In my view mullaans and their supporters have harmed and destroyed muslims in various ways. However the main things they used against them was their misinterpretation of the quranic message and its misrepresentation. These foolish people turned the purpose based proper governing system into a make beliefs system and useless practices.
However muslims are victims of their own self imposed ignorance about the actual message of the quran. Had they prepared themselves purposefully properly for seeking, receiving, studying, accepting and acting upon it purposefully properly then they could not be misled or fooled by ignorant mullaans.
Is it not surprising that people who have phds are following ignorant mullaans throughout muslim world? This is why human beings are suffering terribly throughout the human world by hands of each other because they have ignored, neglected and avoided the actual quranic message.
The quran provides mankind with guidance about human society as to how it should be set up and run so that the human world becomes and remains what it was created for. Baseless beliefs and practices cannot bring about that kind of human world instead people need to think, plan and do what is needed to bring about that sort of human world.
