Your questions are being answered; you just aren't recognizing it because you think you've pulled a "gotcha," and people aren't answering in a way to make you "win."
All of the Holy books of the Abrahamic religions (Christianity, Judaism, Islam) are filled with some pretty vile stuff and can be twisted to support whatever people want. And verses can be excused away with any reasoning people want as well. All you have to do with the Bible is quote a lot of the just as horrible stuff from the Old Testament and use Jesus line about him coming to fulfill the Law, not do away with it to make sure it "counts," and, "bam," you can justify anything.
Western political systems hold Judaism/Islam/Christianity in check in Western countries, and keep them within certain bounds. If, say, Jehovah's Witnesses became their own soverign nation with the Governing Body ruling it, if Mormonism wasn't contained by the country but got their own soveriegn land, or if many hardcore Protestant Denominations got their own countries to rule as they wish, they would be far worse than much of the Middle East.
As I stated before (Pacopoolio - forum software gives me an error when I try to log in on my other computers), the problem is that (most) religions based on ancient holy books can be used to control and manipulate people. While the vast majority of Muslims in Europe and the US are fine, many of the groups antagonistic to the West have that as their religion, and their antagonism is based more on history and geographical location. The causation is the latter, the tool used to manipulate is religion (it just happens to be Islam in this case, but could be anything).
