My doors unlock from the inside, and I alone control that lock. This is completely and utterly the opposite of a border wall controlled by thugs loyal to overlords. Revise your thinking in order to grasp nuance, or remain subject to direction, as you prefer.

Do note the example of the Berlin Wall. Did you never see the bodies of those that attempted to escape East Berlin hanging from it riddled with bullets?

Prior to the introduction of projectiles capable of demolishing physical defenses, walls were great and necessary defenses against military assault. Since immigration is not military assault, walls have almost no impact on immigration. What we observe regarding immigration today is that those seeking ingress apply for asylum. Few sneak over the border and do not apply for a green card.

What does control immigration are the rules of the nation folks seek to enter, and the enforcement thereof. It is facile to end immigration by simply enforcing extant laws that criminalize employing illegal immigrants, as that would quickly end any desired advantage illegal immigrants seek.

I have not addressed the issue of immigration otherwise, so your assumption regarding my political positions are pure conjecture and reveal only your own biases, saying nothing about me.
