"...though it seems clear he is not an opponent..."
If you read the whole interview you find out that Beck does oppose it but thinks there are bigger fish to fry at the move.
I went ahead and watched the interview instead of reading the transcript.
Beck was careful not to take a position on the homosexual judge’s ruling on the Proposition 8 case. It seems Beck’s trying to separate what he considers the “big picture” from various parts of it. All of these “social” issues are important—it’s why our country is “burning.” But when it comes down to bare bones, all issues are “social issues.”
