I know that Orange in Irlenad represents the Protestants, but in America isn't St. Patircks Day more of a Secular day meant to celebrate Irish Culture...?
Yes, in Ireland St. Patrick's Day is more of a religious festival. In America it is an excuse to get loaded, have fun, march around, eat corn beef and cabbage, drink dark or green beer, and act silly.
I am of Welsh decent and I like the music and the dark beer. Yummy. I wear the green so I don't get pinched.
