The answer to that question depends in part on whom you ask and on which religion is being considered. On Tuesday, for instance, voters in Oklahoma passed State Question 755, aka the "Shariah law amendment," which changed the state constitution so that Oklahoma courts are now forbidden from "considering or using" both international law and Shariah law when making their decisions.
Constitutional scholars say that the way the law singles out a particular religion violates the establishment clause of the First Amendment of the U.S. Constitution, but also point out that Shariah law has never been used in Oklahoma court decisions anyway.
"This measure is not about these hot-button issues," CAIR's press release stated. "No one has or will ever propose anything to do with criminal punishments often associated with Shariah. If the sponsors of this measure wished to ban these practices, they could have offered specific language. They did not. Instead, they exploited the growing anti-Islam sentiment in American society to demonize Islam and marginalize Oklahoma's Muslim community."
I can't believe politicians ever thought this was a good idea.
Oh, wait, yeah I can. It was a fantastic way to get the rednecks to the polls, and I doubt many of them were voting Democrat.
