Which is more harmful, known or Muslim?

Islamic teachings are closed and conservative. In history, many ancient civilizations were destroyed by brutal killings. In modern times, Turkey is still using state power to commit genocide against Christians. There is no developed country in Muslim countries except for making money by digging oil. However, Muslim immigrants and refugees have destroyed and are destroying modern civilized society by using uterine weapons and fundamentalist terrorism, which is called' the cancer of the earth'. Maybe the next world war will be a clash of civilizations. Let's wait and see which civilization will win in the end.
