"Same could be said for Israel..."
Good example.
As for uniting Mexican families, they don't need the US government to do that for them. They can go back home and be with their families, just like that. If they didn't want to be separated from their families, they shouldn't have separated themselves from them. I have a feeling that if I emigrated to, say, France, that the French government wouldn't do a whole lot to reunite my family with me over there in France. They'd tell me to go back home where my Family is. And they'd tell me that in French.
As for the open borders and coming and going as you please, it's pretty hypocritical of them who are demanding such nonsense. Their ancestors had that, and they gave it up, for whatever reasons. They could have, and maybe should have, fought a little harder for it. But, instead of questioning the actions, or lack thereof, of their ancestors, these decendents are simply blaming white people. Yeah, like I had anything to do with it.
I wonder what their reaction would be if we just up and gave them the Southwest, but before we did, we ripped up all evidence of any kind of modern infrasctructure. All roads, electricity, buildings, dams, everything. Level it all. See, they don't want what they used to have, they want what someone else built.
