I'm going to try to articulate one of my favorite things about America and I hope that it is clear and not some weird, rambling, jumbled mess.
I love that we love to celebrate the culture of our ancestors here and it no one feels that it somehow takes away from how American we all are. For example, towns that were primarily founded by Germans might have a giant festival in October to celebrate Oktoberfest with traditional music, dancing, and food, but when the Olympics roll around, these people are still chanting "USA! USA! USA!" Families of Scottish descent might have a kilt made of their family tartan, but they still set off fireworks on the fourth of July. From where I am in Texas, I knew many first generation Americans whose family was from Mexico. They held tightly to their culture which always made ti so much fun to visit their houses, but they were never more proud when they told people that they were Americans. I absolutely love it! Because our country is so young, so many of us come from other cultures in Europe, Asian, Africa, etc. and we are able to celebrate those while still being so proud to be Americans.
