OUCH! Good one. Who in America cares about their 100 holidays or their 100000 "holy" sites? Geez, they need to be a little less obvious when invading a culture...
I'm not telling you this to rile you, but my niece's elementary school has Mexican hoidays included with the US ones in order to help the immigrant kids feel better...they just celebrated "Mexican Flag Day" on the 24th. It's one of many they celebrate.
They made mexican food and talked about the three colors of the Mexican flag, Red, White, Green.
They also got to color the Eagle on a Cactus eating a snake and learn about it's symbolism....
My cousin was not amused.
