I am not talking only about islamist terrorists. I am also reffering to other religious practices that the western world would see as barbaric: such as the general practice of keeping women dominated (through the use of FGM, through the mandatory covering with a hijab/burka, through the practice of wife-beating if she refuses to have sex with her husband, through the practice of rape if the woman is unnacompanied by a man, through the inequal treatment in face of trial (the word of a woman counts as 25% than that of a man))
I am also reffering to the practice of killing homosexuals.
I am also reffering to the practice of treating non-muslims as lesser people, and feeling entitled to rape non-muslim women.
I am also reffering to the practice of enslaving people that goes on still to this day in some fundemantalist muslim countries.

I know that most muslim people don't adhere to these practices, but they do exist. And these practices do follow the teachings in the Koran. I know that most muslims just want to live their lives in peace in their communities, but if such a situation would arise where they would be called to vote in order to implement Sharia Law (which endorses most if not all the practices mentioned above) in a country, would you think that muslims would vote for or against such a law, also taking into consideration that other muslims would call them bad muslims if they wouldn't?

I honestly dubt that when push comes to shove, the average muslim would vote for a secular law instead for what their own religion tells them to be the law of God.

In this case I'm going to take the numbers that you presented as true without fact checking, because in my opinion they are of little consequence for this discussion. And that's because Islam has many more abhorrent practices than just kamikaze warriors of Allah driving the truck of peace into the unbelievers. I'm not saying these practices are done by the majority, and I know there are also differences from countries to countries and there are different interpretations of the teachings, and not all muslims take to heart all the teachings the same. But, in the end, all of these practices are codified in your holy writings, and the continued use of these practices stem from the basic belief that the Koran is the word of God (and you'll find many/the majority/all muslims asking "But if the Koran says it's allowed to do this, and the Koran is the actual word of God, how can the Koran be wrong?")

Now let me ask you, let's suppose that you would live in ...I don't know... pick a "western" country with many muslim that at some point immigrated there, doesn't matter which one... let's say Germany. Would you be for or against implementing Sharia Law there? and why or why not?
