Not sure if you are being obtuse or snarky, but obviously I am referring to our right to keep dangerous people out of our country.
A lot of people here have attacked Trump's travel ban as not enough. Maybe not, but it's something and it would help. They have also called it expensive. How expensive was the attack in London?
Apparently, the well-known phrase 'creeping socialism' has been forgotten. Liberals got a lot of things done by creeping.
This travel ban is needed and would be a start.
Stop and END ALL immigration to the US until a new system of vetting can be created, and then only permit a small percentage of immigrants based on existing population divided by national origin and skill sets that are beneficial to American society.
End ALL Refugee resettlement unless they are Christians being exterminated and they can be properly vetted as such.
End ALL welfare or public tax programs for anyone who is not a bonafide and registered citizen of at least a minimum of 10 years.
That's it.
Of course that common sense will never happen.
I'm partial to piggybacking the Johnson-Reed Act, which eliminated mass immigration and severely limited who could come here to this country based on national origin until the existing immigrants from the previous decades were fully assimilated into our own culture, language and society.
However, the Republicans will no more impede the invasion by third world squatters seeking to reconquinista and Jihadists than the Democrats will.
So like Europe, our fate is already sealed.
