Political correctness - Gender-related
The term server is increasingly used for a person of either gender who waits tables.
Chairman was replaced by chair, chairperson (or president or some other term). (The term chair has its own history within academia.)
Fireman was replaced by fire fighter.
Congressman was replaced by member of congress. The former remains in use for male members of congress, however.
Policeman became policewoman when referring to females; then the term police officer was introduced for both genders.
Likewise, Army wife, Navy wife, etc., are now Army spouse, etc. (Occasionally male civilian spouses of military members will ironically refer to themselves as Navy wives, etc.)
"To boldly go where no man has gone before", from the introductory sequence of Star Trek: The Original Series, was changed to "To boldly go where no one has gone before" in Star Trek: The Next Generation.
"Man does not live by bread alone" became "People do not live on bread alone" in the 1996 NIV Inclusive Language Edition of the Bible, Matthew 4:4.
Airlines no longer use the term stewardess (nor steward for men), partly due to disparaging stereotypes and the condescending nickname stews. Thus they have replaced it with the gender-neutral term flight attendant. As is the case within nursing, male members of the profession, who are the minority, are typically referred to by their gender (e.g. male flight attendant as opposed to flight attendant for females.)
The word sex has largely been replaced with the word gender, though gender classically did not mean male/female, but rather it referred to grammatical masculine/feminine constructs ("steward" vs. "stewardess", or "actor" vs. "actress", for example). The word sex seems to have become an impolite or emotion-charged term, at least in part because it is prevailing verbal shorthand for sexuality and sexual intercourse.
Lacking a gender-neutral alternative, many actresses now prefer the term "actor" when defining their profession, thus eventually likely rendering the term gender-neutral through common usage.
TIME Magazine's Man of the Year became Person of the Year regardless of which gender wins it (there had been "Women of the Year" in the past).
The phrase "Whatsoever you do to the least of my brothers, that you do unto me", attributed to Jesus, is frequently changed to "Whatsoever you do to the least of my people, that you do unto me."
Miss and Mrs. have been supplemented by Ms., providing a word that does not indicate marital status. The term was ridiculed by many when it was first introduced in the 1970s, but over time it has become common usage.
The 1960s-1970s TV show The Dating Game needed terms for unmarried contestants; bachelor was obvious, but the feminine "equivalent" was the negatively-charged term "spinster", which was only more slightly polite than "old maid"; so the show either coined or popularized the term bachelorette, which has since come into common usage.
The time-honored "I now pronounce you man and wife" at weddings has largely been replaced by "I now pronounce you husband and wife". Some etymologists find this amusing, as "wife" is Old English for "woman", while "husband" is Old English for "householder"; the original expression was meant to define a moment when both members of a couple officially and legally became equally committed to adulthood.
Generalized uses of man when referring to humanity (mankind) are frequently replaced by gender-neutral terms.
Political Correctness comes to America via a Marxist Organization: Social Research in Frankfurt, Germany, which was founded in 1923 and came to be known as the "Frankfurt School." After the Nazis came to power they moved their operations to America and set up shop at Columbia University. Inspired by the brand new communist technique, Mao, in the 1930s, wrote an article on the "correct" handling of contradictions among the people. "Sensitive training" – sound familiar? – and speech codes were born. When a people become sensitive to the "needs" of others it makes it far easier to make people have a more socialistic political form of government.
I am still trying to rap my mind around the fact that President Obama feels it is more important for people to be required to have health insurance than a job or career.
