If   is so against idols that they smash Assyrian and Buddhists statues, then why do they pray at Mecca and circumambulate the Kabba?
I am not sure what you are reffering to. Are you trying to be offensive against Arabs?
no, because if you read about Islam critically, then you know that this is true. Look at what ISIS is doing and how they are murdering people left and right and demolishing historical sites. Also, if the Qur'an and the Hadith are so perfect, then why do you need idols to pray to?
ISIS are made up of difference people from different nation. They are sick in their head and they joined ISIS an excuse so they can do destructive things without repercussions.
