That's an easy question. If Muslims (whether there were 10% or 60% or 99% of them) wanted to intill Sharia law in this country, I would obviously choose (a). Similarly, if Mormons or Catholics or Protestants or Jews or any other religious group wanted to instill their religious laws in this country, I would choose (a).
I don't accept tyranny no matter what name or religious banner it goes by. But I evaluate individuals on an individual basis, and I don't automatically exclude entire groups based on some (unconstitutional) religious test.
I agree that yranny under any banner is frought with peril. My simple question is will you follow the constitution or will you try to manipulate it into something unrecognizable.
I'm sorry, that sort of thinking - treating people as individuals - doesn't seem to be very popular.
