America’s pledges of allegiance and various showings of national spirit are pretty extreme on a world scale as far as I can tell – several Germans I know were visibly shaken and alarmed at what they saw going on in grade-school American classrooms.
I took some Italian relatives to a drum and bugle corps show about 20 years ago, and they had a similar reaction. All the saluting and overt patriotism reminded them of bad times in Europe. While they were impressed with the performances, they found all the saluting slightly scary.
