There is no "today's definition". I keep telling you people I'm a linguistic archconservative. There is an original definition, and that's what I cling to. There are also people walking around misusing the term, morphing it into its own opposite -- which of course is a contradiction. But that's their problem. I just illustrated this for another poster --- imagine a football field. You're sitting on the 50. Two teams on the field, one trying to move the ball to the left, the other to the right. And each opposes the other. Those are obviously the 'left' and the 'right'. The Liberal, however, is the referee. The ref never carries the ball, never makes a tackle. He just makes sure the playing field is even and nothing takes place out of bounds. And of course from time to time one team or the other doesn't like the ref's call.
