The wall is in reality a distraction from getting anything real accomplished.
Most people know that appropriately utilized border barriers is needed and has been in use for decades. Unfortunately Trump made "build that wall" a rally point for his ever-so-important base, along with the false promise Mexico would pay for it, and tied that rally cry into some very unfortunate fear mongering and hate speech against immigrants and minorities that extends well beyond the issue of illegal immigration (let us not forget his condemning "that Mexican judge" who is a US born citizen of Hispanic descent).
Many of us who are rightfully bothered by that aspect of his campaign came to see "The Wall" as a symbol of that hate. In all honesty, I think many of his supporters see it the same way.
If Trump had better political skills and knew when to keep his mouth shut, policies such as expanded and improved border barriers probably could have been easily accomplished.
I don't see the wall like that at all, in fact I never even thought of that until I saw a CNN headline telling me that's what it was. Yesterday I googled a little to see a replay of the President's address to the Nation and the first two pages were all Lib sources that had crazy headlines like what you talked about above. I never did find the video in it's non analyzed state. I gave up pretty quick when I saw the spin being put on it. I don't look at the lock on my neighbors front door and get offended. He's Mexican and he's trying to keep me a white guy out of his house. How dare him. And you know he's keeping every other color/race of person out too, but that's irrelevant, hes racist because I have to ask his permission to get in. Oh, and I just want some food from his fridge so my family and I can better our lives by eating his wife's FANTASTIC tamales. Come to think of it he has a fence he put up between our properties.......what a hater.
Improved Border Barriers......................... I've heard that term somewhere before.
