And I think that Islam is an ancient form of totalitarianism, to which the very word "Islam", when translated, means "Submission". I don't like it. So sue me.
Submission to the will of God, not man.
It's just a name; Islam, in practice, demands no more submission than Christianity and Judaism.
For instance, while I am not a christian, I like it a lot more. I could even give theological "rational" reasons for it.
I'll address why this seems so hypocritical later.
No, sharia law is islamic morals, it is not islamic theology. IOW, it is how they do about things, not how they think about things. And of course, it's prone to change and "reinterpretations".
Sharia is a set of guidelines and a moral code set down by the followers of Mohammad. If you hate Sharia, then you have to hate Christianity and Judaism for the Pentateuch (the first five books of the Bible; Genesis, Exodus, Leviticus, Numbers, and Deuteronomy).
Sharia demands hands cut off for thievery. Christianity and Judaism demand the death penalty for growing different crops in adjacent fields. Sharia advocates the submission of women. Paul says women need to remain 'quiet' and 'subservient' in the epistles.
On the other hand, the Ten Commandments say that murder is abhorrent, that Christians and Jews should honor their parents, and not to lie about your neighbor. Not only does Islam recognize the Ten Commandments as the word of God (just spoken through an earlier prophet), but they have their own condemnations of murder, of false testimony, and respect for elders.
If Christianity and Judaism were widely practiced in societies that face the same levels of corruption, poverty, and authoritarianism as Saudi Arabia, Pakistan, and Indonesia, then they would be just as savagely interpreted. Western Muslims, by and large, don't advocate the submission of women to that extent, mostly because they live in developed societies where women hold high standing. They don't advocate chopping off hands for thievery for the same reasons American Christians and Jews don't want people killed for growing corn and wheat next to each other; because the Western justice system is more fair and modern.
And you're right, people do live by common sense and just want to live their lives. Sharia, just like the Pentateuch and the Epistles, is open to interpretation and adaption; it has many good principles to live by, but it has many 7th century principles that no longer apply. If we get back to the original topic, you have to consider judicial appointees on a case-by-case basis.
