The concept of politically correct has never really reached Italy.
We don’t even conceive that someone might not celebrate Christmas. We barely realize that Christmas is actually a religious holiday. We wish “Buon Natale” (‘Merry Christmas’) to everyone.
We have a more politically correct expression “Buone feste” we might translate that with ‘Season’s Greetings’ or more generally ‘Happy holidays’.
But the idea of holidays is very different. Holidays include not only Christmas Eve and Christmas day, but the whole period between December 24th and January 6th, l’Epifania.
As we say l’Epifania tutte le feste le porta via ‘the Epiphany brings away all holidays’.
BUONE FESTE A TUTTI!
