Well, for a minority one, "
MY " culture ",has certainly added a very great deal to " AMERICAN CULTURE ". A few examples : " danish " pastry ( it isn't; it's Hungarian ! ), the A Bomb, many movie stars & directors ( who weren't anti-American and actually made great movies ! ), and much more. :-)
I do tend to " catch " the newbie morons. My radar hones in on abject stupidity. It makes my teeth ache.
