Not a single person coming from a 3rd world Islamic country has any bad values? What?
I have absolutely no idea what "Values" are supposed to represent in this context so I'm going to assume it means basically nothing relevant. If they can get through the immigration and vetting process, there is no problem.
If after letting them in and there is an all across the table unanimous agreement that the migrants immigrating here is directly corralated with any sort of increase in terrorism, maybe then would this argument hold water. Until then, eeeeeeehhhhhhhhhhh
