POLL: Dave Ramsey fired a dozen employees for having premarital sex. Is that ok?

Ramsey Solutions, the company founded by evangelical radio personality Dave Ramsey, has admitted to firing at least 12 employees in recent years because they were having premarital sex. The admission comes in response to a wrongful termination suit filed by former employee Caitlin O'Connor, who says she was given the boot for becoming pregnant out of wedlock. A spokesman for Dave Ramsey says O'Connor wasn't dismissed because she was pregnant; she was let go because she violated the company's "righteous living" policy. He defends the move by noting several employees have been fired for the same reason, and "most of them weren't pregnant" at the time. Outside of pregnancy, would it be hard for a company to prove someone is having premarital sex?​
