At some point between the grilling and the fireworks, everyone should take a few minutes to actually sit down and reread the Declaration of Independence. http://www.archives.gov/exhibits/charters/declaration_transcript.html
The 4th of July is not about blind nationalism towards the United States. This is a day for celebrating the vision of liberty that Thomas Jefferson laid out in that most important document presented to the Continental Congress 237 years ago today.
Perhaps instead of handing out American flags on this day, we should be handing out copies of the document that this day is actually about.
