It's really not though.
By Western standards, America is a very conformist country. You can see this in how schoolchildren are required to pledge allegiance to the flag, to the slow acceptance of gay rights, to controversy over saying over "Happy Holidays."
I deeply wish America was a country that supported individualism in the sense of supporting and even celebrating the right to live your life as you see fit.
All too often, however, it seems that this love of "individualism" only surfaces when someone needs help or asks for cooperation.
That's not individualism. This simply selfishness.
