Oh my GOD it is hard to believe,BUT it is true.what your,s opinions are?

Now i came to know that why head of islam want to kill the writers if they write something against the Islam ,that they do not agree with.because they can not have the right answers to satisfy the writer,and they put the price for the writer,s head.like Fatima d/o Prophet Mohammed married her real uncle Ali.and Prophet Mohammed married 11/13 times when his youngest wife Aysha was 6/7 years old and he was close to 60 years old.i just red and ask my friends who are born in islam and guide me to find out ,because i was not able to believe this.please do not take in otherway but be sereus to answer,and better you ask and make sure about it because i still not believe it.thanks for your kind answers in advance.thanks.
