Reality is that its a universal problem. Every religion or ideology would want to have all people under its own law. A Muslims government in India would want to enforce shariah on the Hindu population. That's why I prefer the community based non-monolithic state where each community stick to their own laws and courts. It would take a miracle for secular liberal non-muslims with a significant strong population to ever live in a state where shariah is enforced on them. Apocalyptically speaking, when Gog Magog would be wipped out of earth then only would islamic order and golden age be achieved in totality.
