I do not normally respond to comments. It is my belief that once I have said what I have to say, it is best to let the combox take on a life of its own. I am delighted when readers debate each other there. I am even delighted when readers just rant at each other. The exchange of opinions is a good thing per se, even when it is accompanied by the throwing of rhetorical elbows.
But, last week, I wrote a post about immigrants that both examined the results of a new Pew study and suggested that it would be helpful if the Congressional Budget Office could calculate what effects comprehensive immigration reform would have on extending the solvency of both the Social Security and Medicare trust funds. The comments of Professor Carmen Nanko-Fernandez on that post are such that they deserve a response.
