What is worse is that someday they will make the American Govt pay them reparations for allowing this to happen.
I can't see any legal issues for reparations.
What's at stake though, is the claim of "today we march, and tomorrow we vote." The recent protest organizers tried to sell Hispanic illegals that they can register and have the legal right to vote. I'm going to put my flame proof suit on again, because years ago I used to be against national ID cards. Not anymore, I'm now for them 100%,
The American taxpayer pays all the costs of the American gov't. Yes, you and I pay the bills.
