Any legal system based on superstitious origins that imposes horrific disabilities on half the population and presumes to dictate what and when people may eat is not one that can ever be acceptable to any human who is self respecting and regards freedom as more important that obeying the dictates of a pack of lunatics. Shariah has incredibly primitive attitudes--chop off body parts as punishment, punish blasphemy (if your frigging god is so powerful, let it punish it's own blasphemy, not depend on humans to do it),, and impose itself on people who darn well don't want it.
