Dr. Ben Carson has said that a Muslim shouldn't be president. His comments aren't acceptable.The Constitution guarantees equality before the law. While we all know that the social reality lags behind that ideal - and so does the law itself, on occasion, when unfairly applied - we have every right to expect that a U.S. President will faithfully execute his/her office to uphold, protect and defend the Constitution. There will be no religious test for public office. None. Anybody who can't be reconciled to that requirement, has no business running for president.
