I agree with what most of you are saying, everyone has the right to say &/or believe what they want. But there are repercussions for your actions. Rather you think it's right or not, he's being bashed on every news channel nation wide!
Time Entertainment said it pretty good:
That presents a problem. Now, you’ve got an issue with those of us who maybe just want to watch a family comedy about people outside a major city, but please without supporting somebody thumping gay people with their Bible. Or a problem with people with gay friends, or family, or, you know, actual gay A&E viewers.
And, once you take any kind of action on that, you’ve got the opposite problem — with deeply religious viewers who like the Robertsons for their faith. They’re going to see it as you punishing him for saying out loud what he believes, and maybe for what they themselves believe, and what they believe is the word of God. You’re punishing him, in their eyes, for being one of them.
