It's a BS argument. Almost everyone you and your Orange One claims wants open borders doesn't want open borders. It's a lie in order to keep the pot stirred. It's a Hey, look over there routine so that maybe, maybe, we won't notice the other crackpot deeds. You can stop lying any time now.
Except they oppose every measure proposed to close the border.
You're just another lying leftwing sack of shit.
Hey, stupid, your stupid fantasy argument will never happen. You cannot actually completely close the border. Well, not until they invent Force Fields, that is. And then to have that force field, we are going to have to spend over 50% of our GDP to pay for it and maintain it. And we are at least 100 years away from anything like that. Even then, I am sure, that some evil Genius will come up with some sort of Frequency Modulator to get around that. The present idea of the "Big and Beautiful" wall is tomorrows Force Field.
The Chinese had a brilliant idea for a Wall too. They spent generations building it. They spent entire nations fortunes on it. They spent millions of lives on it. In the end, how effective was it? The Mongols just went around it and invaded anyway. The horse beat the wall. The Chinese just didn't have enough money nor people to ever get that wall completely finished before the Horde came crashing in. All the Wall did was slow them down and look real nifty from Space.
Considering most of the problems have come from the Newly Elected Presidential Policies, I think you have better look at the Orange One for the solution, not Congress who knows that you don't build that wall overnight and has budgeted it that way since 2006. If you can't do that then you need to go to the border and start patrolling there yourself.
