So, 241 years ago we had that whole Declaration of Independence thing. The July 4th holiday is always a good time to think about what true patriotism is, and to think about history a little— especially about the lessons of history for the moment we are living in right now.
Patriotism at its best is the kind that loves our country passionately, treasures what is great about it (which is a lot), but also looks honestly at our flaws, past and present, and resolves to make our nation better.
