It just so happens that the extremists' opinion is based on sound Islamic doctrine. The majority opinion does not matter because a) it is not in accordance with what Allah orders in the Quran and the Prophet's example and b) it is the extremist opinion that causes the violence.
I do not think you are fake - I think you are simply too nice a person to be violent to others, but at the same time, you seek to defend the beliefs you have been brought up with.
You can call me a fundamentalist, but I am not saying anything that the Quran is not saying. I am using Islam's own sources - Quran and Hadiths - to question it. If you question the foundation of my criticism, you question the foundation of Islam.
Of course you do not like to be told that you do not understand your own religion - no one likes being told that. Centuries ago, people believed that the earth was flat and did not like anyone telling them that it was in fact round. But facts are facts, and we have to come to terms with them.
