I am by no means a madman or even a moderately paranoid, but you sound like an apologist for broken borders.
I would have suspended immigration for any reason of youths under the age of 30 until we get this whole "Is it an ideology like communism or is it a religion figured out." I think we are tending toward it being an ideology like fascism or communism. We do not need more Dearborns in this country (thank you Henry Ford) until the whole Iran/Al Qaeda/Islam will dominate the world issue is rectified.
Known fascists and communists weren't openly and legally "exchanged" into this country when they were a popular threat.
That would have been, well, lunacy.
