DJS » Most all of what Simon has said I have said many times on this site. Unchecked immigration can't be absorbed by any country on an ongoing basis. The US has been more than patient, generous and benevolent.
Yes, and the U.S. has major problem with population. Not too many people, but not enough to sustain the baby boomers who are expecting to get their Social Security, Medicare and other entitlements.
That said, Europe let in thousands of Muslim refugees and they have repaid their kindness by kicking their benefactors in the teeth: by posting their own rules based on Sharia Law, tearing down and threatening violence over Christmas decorations and overturning cars and setting them on fire. Is this something we need here?
We need Mexican influx because most are already Christian, they're hard working, and the ones I knew in southern California kept their Christmas lights on all year round. They had great food, too. So, who would I rather invest in? Hmmmm.
Mexicans. Any day. And even if we get good Muslims into the U.S., many times their children and grandchildren are radicalized. Many are good people, but we don't have a way of vetting them or telling who will decide to buy a gun and take out people at a shopping center. If we can keep the drug dealers out of the country, we can do okay with Mexican immigrants.
Besides, I don't want to give up my guns or my Christmas lights because some idiot decides to go jihad down the line. JWs don't like Christmas decorations, either, but they don't go out and kill people (unless they need blood transfusions!).
