Our English language can evolve very quickly. There was a time when writing style guides for publications said "gay" was unacceptable slang, and the correct word was "homosexual". Editors at newspapers & magazines would remove "gay" as slang, just as they did with other colloquialisms and slang, replaced by more "professional" terms.
I remember a Jay Leno Tonight Show "Headlines" from the 1990s, showing a newspaper noting the August anniversary of the atomic bombing of Japan. The B-29 aircraft that dropped the bomb was named the "Enola Gay" after the pilot's mother. But the headline was edited to say:
"50th Anniversary of Enola Homosexual Bombing of Hiroshima"
Nowadays it appears they would have gotten the headline correct.
