These comments are indicative of two things. First, the Religious Right and its allies don’t understand the First Amendment. Robertson has the right to say what he said. But freedom of speech doesn’t mean you get to say whatever you want whenever you want without consequences. Robertson spoke his mind; A&E has the right to suspend him as a result.
Second, this incident shows the ongoing power of the Religious Right as a voting bloc. Cruz and Jindal each have a reasonable chance at being presidential nominees in 2016, and they clearly both think evangelical voters will be necessary for them to win in Republican primaries. They’re right.
