That is a warped view of history IMO :), America was born out of the idea that we can make a better place for everyone, one where everyone counts and has a chance to build the life they want (historically a big one was to practice their religion without discrimination as well). It wasn't born out of revolution, it was born from people escaping British society in order to live a better life. And, regardless that was a long time ago, we've reinvented it since then, it is a land of immigrants who want to build a better life for themselves.
I believe American Culture is one that supports each other and society, we have just lost our way and we are in a bit of a battle for the soul of America. It is being hijacked by super individualist who forget they are part of something bigger and that they have a responsibility to society as much as society should respect the individual.
If you have a bike accident people will stop to help. If your car breaks down, people will stop and help. If you have a medical emergency, people will stop and help. If you need directions people will help. The media likes to show fear and we think that is the norm, when in fact the vast norm is that we are always going to help our fellow humans. Cops are still human, despite really bad training that causes them to fear everything and everyone. If a cop asks you to stop and the only thing that makes you stop is the threat of violence I would seriously rethink who I am and my values.
