The author appears to be some kind of moron. If the fence exists everywhere and it is effective, why do we have millions of illegals in the country?
It’s hard to tell the difference between a liberal and an actual moron - they support the same things. Usually, the liberal is the one who is unable to see their own stupidity. Actual morons usually want to learn to be smarter.
They show city area walls like San Diego etc. What about that rough border area in AZ where ranchers are killed on their own property by illegals on high ground?. How about Texas?
A lot of them are visa overstays, arrive by air, and millions upon millions of people here legally who don't belong here.
Don't get me wrong - I'd seize a ten-mile strip into Mexico, bulldoze and dynamite any structures, mine it and THEN build a fence.
But our problems are much bigger than the border.
