If ObamaCare and Cap&Trade pass, it’ll be worse here. At least there you can still wish a person “Happy Easter” or “Merry Christmas”.
Other than dirty looks, nothing should stop you from saying Merry Christmas. Since you brought this up, why are so many people in the northeast who are upset about the whole "Happy Holidays" issue not even regular church attendees or bible readers?
BTW: Italy is 19th on the list.
