I like the term "undocumented Democrat" as a replacement for "illegal alien" which offends the sensitivities of people in Cleveland, Ohio, who don't live near the Texas/Mexico border.
"Gay" used to be a pejorative (addicted to pleasure and dissipation), but has come into its own, and now even "queer" has become quite acceptable, as is "trany."
I think, since the word "holiday" comes from holy day (hāligdæg, hālig "holy" + dæg "day"), we could compromise with "Blessed holy days" as an acceptable substitute for Merry Christmas, bringing in Advent, Christmas, Epiphany, and any others who want to join in on pleasant greetings of the season. The Bible used the Greek word makarios, which means to be happy or blissful. So why not have a happy blissful holy day?
