Immigration is pure evil - unless it is so limited that it does not move the needle. Then why have it?
Justifying immigration because you need workers is bs. If you need workers the way you need a plumber, let them in for a year and out, no matter how good they are. Men only!
Also, delete "asylum" from your vocabulary. It's a fraud. Asylum is temporary for friendly neighbors, not some a-holes in Africa that like killing each other or because they are poor.
Exotic fruits, insects etc, but people? Just........no.
Exotic insects are easier to deal with. Just spray them and they die.
You can't kill exotic migrants. In fact, they are treated better than the locals when they rape. "He didn't know that raping women is a no-no". No, I am not making it up...
