This country was based on a citizenry wanting and working toward the same or similar goals. There are reason many American choose not to live in Africa, Mexico, China or Europe, because we don't like nor want their culture or way of the live. We prefer to live here in the US governed by our constitution, because with the constitution we are governed by the rule of law and not rule of man. At least we use to be, thanks to your wonderful diversity we have been moving away from those principles and we are slowing watching our constitution being neutered by the big government elitist. 
Now with that be said why should be forced to change my way of life in order to satisfy your desire for diversity? What was wrong with the way I have been living for last 70 years?
