Not everything is up for interpretation in Islam. For example, homosexuality is prohibited, and no amount of "interpretation" is going to change that. Same goes with drinking wine or intoxicants. There is no valid interpretation of Islam that allows such behaviors. You'd be surprised to find that said "religious leaders" you're referring to don't know the basics of exegesis. This applies to ISIS for example. I invite you to read the many Hadiths about Khawarij, those immediately reject your premise that all interpretations are equally valid. They're not.
