...just pointing out that this quote does not support the argument against it.
I will disagree. Such a "best reading" produces superfluous, unnecessary language. IMO, it is clear from a fair reading that the language following "who are" refers to three separate and distinct classes of non-citizens.
But otherwise, I have enjoyed reading your various posts! Have a nice weekend (may I recommend the waters off of Santa Barbara?)
I would agree if the sentence said "foreigners, aliens, and the families of ambassadors and foreign ministers." Then that sentence would unambiguously identify three distinct groups.
Thanks for being willing to disagree in a civil manner. That is becoming an increasingly scarce trait around here, I'm afraid... :-)
