As a certified WASP (more or less – a white male heterosexual American of English descent with admixtures of Dutch, French, and Welsh), I’m probably the last person who should give a perspective here.
But it would be my thought that a significant part of what is wrong with America is the focus on small-group identity. Certainly there are valid and laudable things that one derives from being Black, Jewish (ethnically and/or religiously), any of over a hundred ethnic groups, a Californian, a Southerner, a Texan, gay, transgendered, of a given age group, etc. But when belonging to one of these groups transcends one’s sense of being an American and a human being, with rights from and responsibilities toward all other Americans and all other human beings, one begins to forge a divisiveness that leads to conflict and problems.
There was a rather lengthy bit of commentary some time ago on the Rev. Dr. Martin Luther King, Jr., in which it was pointed out that what he is renowned for is not merely what he did for Black Americans, but what he ended up doing for all Americans, in terms of a new paradigm on how to effect change, a new sense of freedom within responsible bounds, etc.
We are the richer for Greek delis, Yiddish writers, les droits de l’homme, Sinterklaas, William Tell, opera in several languages, kielbasa, blutwurst, Goethe, the King James Bible, Shakespeare, Voltaire, Rabelais, Sibelius, Smetana, Kafka, Mozart, Beethoven, bagpipes, smorgasbord, Ibsen, Gregor Mendel, Leonardo, Wilde, Nikola Tesla, Sun Tsu, Hiroshige Ando, manga, anime, Thai cuisine, Zen, … But they all contribute to a common heritage in which we all share.
