I think it's important to distinguish between a religion or ideal - say, Christianity, or democracy - and what people do under that name. If church X doesn't follow the clear teachings of Jesus, that doesn't reflect poorly on Jesus, but on church X. If nation Y has rigged elections, that doesn't reflect poorly on democracy, but on nation Y.
It is important to be able to ask theoretical questions like "is capitalism inherently flawed?" and separate them from "how is it being practised in this situation?" If capitalism + government meddling = failure, it's unfair to say that capitalism failed. Rather, we should say that capitalism wasn't practiced.
I think the poster is just asking for the same kind of logical distinction.
Granted, many of them limit shariah law, such as in the case of Jordan, which limits it to "matters involving personal law such as marriage, divorce, inheritance and child custody." But they still have it.
I wouldn't say countries like UAE, Kuwait, Turkey and many Mediterranean islamic countries are way behind. It also helps that Western countries are eroding mentioned freedoms and values themselves. See for example burqa ban in France. Now that's what I call a country without a freedom of religion.
True, France has had some steps backwards lately, such as the expulsion of Roma. However, I think it's still reasonable to hold the middle eastern countries to a higher standard than they currently maintain. So I'm not sure what you mean by "it also helps that Western countries are eroding freedoms"; it helps who? what?
Anyway, I absolutely agree that Arab peninsula states still have some horrific human rights issues to deal with, especially when it comes to foreign and especially "third-world" immigrants.
But that brings us too far from the original discussion concerning Sharia law because that has nothing to do with immigrant rights, which they essentially don't have being treated as second-class at best or slaves at worst.
Keep in mind that there are four big schools of thought (and that's just in Sunni Islam). Saudi Arabia and the gulf conform to one of those, and it's traditionally more conservative.
So it is only after you've voluntarily agreed to be bound that the court can proceed.
