Really, this sort of column is a sign that the pro-immigration neocons are losing the debate.
I have been emailing with Jeff Jacoby for years. He is always polite and friendly (and yes, he has quoted me in the past. So obviously, I like the guy). But he seems to have an emotional attachment to immigration that no amount of reason can penetrate. Ask him why he is not better informed on a subject that is clearly very important to him (jacoby@globe.com). And please, be courteous and polite!!
