Don't throw out the baby with the bath water. Nobody has ever liked everything about the US. Not even George Washington. If you can't appreciate the good about the country just because you're paying attention to the bad currently then you should have never celebrated it in the first place because the bad was always there.
The things you dont like about America don't have to be your complete view of the country or its history. If there is even a small thing you have ever liked about the country then the 4th is for celebrating that.
Celebrate our victories. Celebrate our culture and our successes. Celebrate how mad people are going to be at you for celebrating. Celebrate that there are like-minded people elsewhere in the country. Real Americans in hard times and with doubts. Celebrate our history and our positive contributions to the rest of the world.
Celebrate a possible and hopeful future of what comes after.
I'm sorry your view of things is so bleak. I'll fire off an Excalibur round for you Friday.
