My point in using this paradigm, was that your statement saying that immigration laws have never been more strict than they are now, was inaccurate. The fact is that even after September 11th, immigration laws are not much stricter than 10 years ago, and certainly no more stringent than the Alien and Sedition Act of 1798, the Chinese Exclusion Act of 1882, or the National Origins Act of 1929.
If the current immigrations laws were actually stricter than "ever before", than the United States would have banned all immigration from all countries known to harbor or appease terrorist cells, because that would have then been at least equivalent to the past immigration laws I had listed above.
