It's not clear to me what it means.
Ok... She seems to use a turn of phrase, anyway this statement is quite old.
I interpret the alleged comment, if true, to mean that Miers' personal convictions are that homosexual behavior is wrong and should not be decriminalized. In a separate question, she flatly said she would not support repealing Texas' anti-sodomy law. People on both the left and right seem to be misinterpreting her responses to the homosexual activist group's candidate survey. As president of a pro-family group that's routinely labeled "anti-gay," I could have answered those survey questions the same way she did. She certainly wasn't committing her support for their agenda...just the opposite in those cases in which she answered definitively.
And I assure you I'm no Bush sycophant straining to find reasons to support her nomination. I wish he'd nominated the conservative equivalent of Ginsberg, someone with a clear record whose words we don't have to parse to try to figure out if she's one of us, so to speak.
