Hallmark is apologizing for changing the lyrics of "Deck the Halls" from "Don we now our gay apparel" to "Don we now our fun apparel." This has been cited as an example of "homophobia," the artificial word created to signify prejudice against homosexuals.
It shouldn't. When you change the meaning of a word (as in making "gay" mean "homosexual" rather than/as well as "happy,") it's perfectly reasonable for people who use it to distinguish between the old meaning and the new one. And if gay activists haven't heard the snickers which have accompanied "Deck the Halls" lo these many years, they need to do something about all that earwax.
The fact is that in common usage the old (and largely archaic) meaning of the word has given way to the new one, and Hallmark was merely taking note of that fact.
