“Why not Christianity, Buddhism or Hinduism Laws?”
This is a very tired, old reaction to anything involving any proposal to revive the Shariah. You will see non-Muslims going up in arms against this idea, even though it is merely at a proposal stage and yet to be properly formulated on how the framework would be or how it will affect both Muslims and non-Muslims. I think these days that is the same case with anything that involves the word “Islam” in it. Nevertheless, it is not my purpose in this post to talk about the Shariah or an Islamic State in Malaysia. That, we can leave for another time. What I want to answer is the insinuation is that “Christianity, Buddhism and Hinduism” (or for that matter, any other religion apart from Islam) have a clear and concise idea of what constitutes “statehood” or even has a proper legal framework.
