Final answer:
President Kennedy's 1963 Civil Rights Address means that when the rights of one individual are compromised, it affects the rights of all. This principle is aligned with the Fourteenth Amendment's equal protection clause and was foundational to the Civil Rights Act of 1964.
Step-by-step explanation:
President John F. Kennedy's 1963 Civil Rights Address expressed the sentiment that "the rights of every man are diminished when the rights of one man are threatened."
Another way to say this could be "everyone's rights are compromised when an individual's rights are at risk." This reflects the principles enshrined in the U.S. Constitution and the essence of the equal protection clause of the Fourteenth Amendment, which emphasizes equal rights for all citizens."
Kennedy's address, encapsulating the ethos of the American creed, aimed to unite all Americans in the struggle for civil rights, resulting in the Civil Rights Act of 1964, which significantly advanced the cause by prohibiting discrimination based on race, color, religion, sex, or national origin.
