I think it was pretty well said after your post, but to reiterate, he didn't come out and say he was against the policy or her endorsement. He was enforcing the lawful regs as far as I can tell, but he (and I) are entitled to our opinions. I don't have to agree with the new DOD policy of same-sex marriage benefits but it is the law and if I'm in a position to affect it, I will make sure that the law is followed.
But that's not enough, I have to conform not just outwardly, but inwardly. My thoughts can no longer be my own, only what have been approved and endorsed by the reigning authority or popular public opion. That crosses the line. And it's downright scary.
