not sure why i'm wasting my time responding to someone i think lacks basic logic, but here I go:
therein lies the problem.
they aren't isolated. they aren't rare. it every single day and sometimes multiple.
the fact of the matter is, the border is broken, they are coming through en masse and unvetted.
you can stick your head in the sand all you want, but the tenor of the country should tell you all you need to know.
blaming it on xenophobia is lazy; blaming it on lack of empathy is inaccurate; most rational human beings want safety for their community.
if you think differently, why don't you house a few illegals you know nothing about and see how that works out.
