We need immigrants since Americans including many recent immigrants have decided not to reproduce (I am guilty on this point, only one son). If we follow the German model, we will bring in Western Civilization haters who worship a murderer called Mohammad who want free stuff and have no skills.
A better model is to choose people who love freedom, have critical skills, and want to embrace our culture. Everyone wants to come to the U.S., we can be selective.
As for CentralVa thoughts: I reject them completely.
I reject Free Traitors™ completely. I’ve watch the population DOUBLE since my birth so stuff it.
