The Essence of Americanism
The essence of Americanism is not necessarily the convenient selective hearing but the convenient agreement to pretend not having heard; even if the undesirable thing gets said out loud, oftentimes very very loud.
How loud should you say things in America to break up the culture of pretending of not hearing?
I don't know; the agreement to pretend is very strong and when opposed one can get a bloody nose very fast.
It does require a lot of personal courage to break this up. However most of the time that essence is explored and monetized by smart people. They become the taboo breakers and they alone are paid enormous amounts of money whose only purpose is to make sure the rest of us continue pretending.
hmm...
