You're comparison would be valid *if* Islam had experienced anything like the Enlightenment. It hasn't. Categories of Left/Right and Conservative/Liberal simply do not apply when one is discussing a political system based upon a revealed religious text.
"You're comparison would be valid *if* Islam had experienced anything like the Enlightenment."
And by the way, as you say, Conservative has a different meaning in different contexts. And that's why you (or others) shouldn't take offense simply because you may also be a conservative. I don't mean to infer any similarities between Islam and Christian convervatives...so relax.
