The point is your parents, or their parents, were immigrants. But those very same people we are now trying to restrict from coming here.
Meaning, if we time travel and apply these restrictions, you yourself would have never been a citizen. In fact, you probably wouldn't even exist. Do you see the problem?
That, my friend, is ladder pulling. When you destroy the very conditions that allow you to thrive.
The entire world has been settled and resettled. You can't let past conquests stop you from having a country, laws and borders or all countrys would be illegitimate.

Or my parents, parents, parents, parents, parents, parents were... And if they came here for a better life, obviously there was some mind virus that was going on in their home country that forced them to leave in search of a better life. Don't try and bring that mind virus here if you had to immigrate here to escape it.
