Humanity does not suffer from the disease of wrong beliefs but humanity suffers from the contagious nature of the lack of belief. If you have no magic with you it is not because magic does not exist but it is because you do not believe in it. Even if the sun shines brightly upon your skin every day, if you do not believe in the sunlight, the sunlight for you does not exist.
This is a good time to ask apologists for the Islamic regime, who degrades Islam? Who imposes stoning, forced marriage of underage girls and flogging for not wearing the veil? Do such practices represent Iran's ancient history and culture, its ethnic and religious diversity? Its centuries of sensual and subversive poetry?
