The catchword in liberal circles today is the term “diversity”. A few years ago the catchphrases were: affirmative action, racial preferences, and racial and ethnic quotas. Since those terms were not warmly embraced by many in the general public, the “diversity” proponents have latched onto the term “diversity” as a more moderate acceptable term to overcome the negatives that those other terms conveyed.
The term, “E Pluribus Unum”, was and is a traditional motto of the United States that appears on the “Great Seal” and on some of our currency. This motto was never codified by law, but it was the “de facto” motto of the United States until 1956 when the U.S. Congress adopted the phrase “In God We Trust” as the official motto. So, even from the beginning of our democratic republic, the main idea of the founding fathers was “unity” not “diversity”.
