That's the big rhino rampaging around the room that the media ignores. Sullivan left the conservative side only because of that issue. Everything else is balderdash as far as his reasons for joining the lib crowd. That's the only issue that matters to someone like Sullivan. Like abortion for the fem-nazis, the gay rights crowd can only see one issue.
Amazing that gay marriage was never an issue when Clinton was president but as soon as Bush got in office it became issue #1.
