Sorry, but I fail to see what is “childish” and especially “nonsensical” about it. The immigration issue is clearly not nonsense. And regardless of what you think of the Pope — whether you regard him as your divinely anointed leader or as just another human — the fact is that the Church has been pushing their agenda on this issue, and Tancredo is not willing to stand idly by while it happens.
There was quite a bit of anticipation and expectation from the Hispanic community, and indeed from his own Hispanic Cardinals and Archbishops, as to the whether the Pope would address the plight of undocumented workers. There were many news articles prior to his visit that speculated on what the Pope would say on the subject.

Also, a commentary titled The Political Pope that is worth reading:

Finally, breaking with Vatican tradition, this time the Popes sermons were delivered in both English and Spanish.
You may think that the Pope is above criticism on this issue, because he is the Pope — and that any criticism of the Church’s agenda is “childish” and “nonsensical” — but the Pope needs to butt out on this issue, period.
