I haven't directly accused him of being non-Muslim, did I? But it requires deep ignorance in religious matters to believe Islam and laicism can co-exist. He once said he hates nothing more than MB, calling them beardies(similiarity between kemalist jargon and his). Hates nothing more than MB as if his country run out of enemies? And worst of all, celebrating the death of a 17 years old girl? Islam is a religion not only adjust individual's life but also social life and state government. To be a Muslim you must accept it as a whole. There is no such a thing as ''i like this part of Islam but i don't like this part''. A Muslim simply can't replace Islamic law with man made laws. Even if he can't do anything about, living in a secular state, he has to condemn it in his heart.
In this matter it is an obvious struggle between Muslim and non-Muslims. There is no other way put it. Is it really difficult to understand? When you get confused just look at who is taking sides with whom carefully. Who are celebrating the coup in Egypt?
Again a Salafi muslim would consider you and your brotherhood non-muslim. I'll give you a test:
Do you believe Slavery should be legal?
Do you believe apostates should be executed if they do not repent?
Do you believe homosexuals should be executed?
Do you believe Marriage should be legal regardless of the age of the wife as long as she has bled?
Do you believe married adulterers should be stoned to death?
Do you believe unmarried adulterers should be flogged?
Do you believe that Democracy should be replaced with a monarch like Caliphate system?
Do you believe that Christians and Jews in Turkey should not be allowed to run for high offices nor join the military and pay a Jizya?
Do you believe that people who aren't muslim, christian or Jewish should not be allowed to live in Turkey?
Do you believe that if Turkey were to go to war with a european country, its okay to take young women and young men as slaves as loot?
Answer the questions with yes or no and why if its no.
If you answer all yes then I would consider you a muslim by your own standards.
