Jackboots always come in matched pairs, a left boot and a right boot.
No, not only should they not be given any form of amnesty, they should be denied citizenship, perhaps permanently. At the very least, they should go straight to the back of the line. Why in the world would we want to give citizenship to people who have already demonstrated a complete disregard for our most basic laws?
Marrying my brother DOES NOT automatically give her citizenship. It doesn't even automatically give her a pass to be in the US.
As for "issues" that should be dealt with on a case by case basis my sister is not unique. Many of them have back stories that would make you think twice about telling them to "get." Many of them were brought over as young children and know next to nothing about Mexico - usually once they come here illegally they never go back for fear of not getting back in. So if you're brought here at age 2 it's unlikely you know anything at all of Mexico and it's highly illogical to deport such a person as an adult.
There are very few cases that would be "easy" unless they are caught shortly after coming here.
For most of them the families are entrenched in the US with many members born here.
I freaking admire them. I know if I was poor and lived in a land of zero opportunity and all I had to do was have the balls and the courage to get across a line drawn on a map and birth my kids on the other side of said line in order to change the destiny of generations of my bloodline to come I'd do it. I'd do it proudly.
That is what you're up against.
You can't stop them from coming.
Abolish all immigration controls and pay reparations to the families of those killed trying to cross the border, all those deported, assaulted, and harassed in the enforcement of insane laws based on the absurd notion that all people born here are chosen people of God, and all others (or perhaps merely all brown people not born in this country) are subhuman.
