That's some "aside" you noted. Maybe you can tell that "aside" of yours to the family members of the 16,806 American Catholics who died during the Vietnam war. And from there you can do a little research and see how many other Catholics died during America's other wars.
On another "aside", where do you get all that propoganda you like to read? This thread was about Flag day, not your little problem with American Catholics.
A Catholic teacher of mine, and transcripts of debates in the Colonies by the prominent men of the day. You are vigorous in your defense of Catholicism; don't you think the question is valid?
