A physical barrier on a nation’s border is a-moral. Neither immoral, nor moral, but rather a physical entity created for some purpose. The purpose may be immoral, like the Berlin Wall, designed to keep people from fleeing communist totalitarianism imposed by force of arms by the might of the Red Army. The purpose may be moral, like the Israeli border wall designed too keep suicidal terrorists from blowing up teenagers at a pizza parlor.
So what would be the purpose of a wall on the southern border of the United States? To keep people from fleeing to Mexico to avoid the strictures of the Bill of Rights? Or to reduce the incidence of MS-13 gang-bangers killing junior high-school students on Long Island?
