Christmas, or what?

'Tis the time of good cheer and I'm irritated.  Is it Christmas, or what?

Why all the "Season's Greeting" and "Happy Holiday Wishes"?  Isn't it Christmas?  Can't we say, "Merry Christmas" anymore?  Christmas is an official federal government holiday.  It isn't a "Holiday" holiday.  It isn't a "Holiday Tree".  It is a "Christmas Tree".  It isn't a "Holiday Card".  It is a "Christmas Card".  Walmart has a large shelf full of "Holiday Cards".  I had to really search to find a few "Christmas Cards".  I notice that most of the cards we've received do not have the words "Merry Christmas" printed on or inside the card.  The senders are hand writing "Merry Christmas" on their cards.  Why do we have to do that?

Over 85% of the population of the United States of America professes to be Christians.  Why can't we, the majority, celebrate Christmas?  Why can't we have Christmas Trees and Christmas Cards?  If you are offended because we want to celebrate Christmas, then too bad.  Go some place else and see how tolerant they are of your intolerance.
