In the sense of fair play, I use the term wall where we actually built a fence. Minor distinction but still different, and actual wall would both probably cost more and be a more imposing and harder to traverse physical obstacle. I just didn't want to alternate between the two terms. If this offers the opposing side in this arguement greater advantage, so be it. As I am sure as Trump figured out that "build a fence" just doesn't have the same ring to it.
Fair is fair.
Fair is fair.
