America has had many periods where immigration was stopped completely....are people really this ignorant of history??
People seem to assume immigration to America was always the free-for-all it is today, which is totally ludicrous...
America for its first 200-some years ensured that 90+% of its immigrants came from Europe. there was a total stoppage of immigration from the 1920's to the 1960's, when the democrats decided to open our doors to millions of 3rd-world immigrants, which ended up resulting in the Obama presidencies. various groups have at various times been blocked from immigrating, even by democrat presidents.
it is laughable to see all these morons, esp journalists, saying how it would be 'unconstitutional' to put any sort of check on immigration. it is not only completely constitutional but also common sense, something sorely lacking in our hyper-PC era.
