I see nothing wrong with that, he was merely voicing his stance on the issue. I share his views on the matter, but not basing it on religion like he does. Unless he goes out of his way to directly prevent a gay couple from being married, why should anyone be offended? Aren't the gay community demanding others to be more tolerant on their views? Why can't they practice what they preach when it comes to this issue? He was asked a question and he answered it truthfully unlike most politicians nowadays who'd just jump on the popular social/religious/political view bandwagons despite believing otherwise merely to attract more voters (I'm looking at you Obama). He didn't come of as inciting hatred nor did he preach or sound condescending.
