Point taken. But it's crazy to say that anyone is trying to "take away" Christmas as a holiday. There's waaaaay to much money being made for that to ever happen.
There's waaay too much money to be made catering to ALL denominations whether they are Christian's who celebrate Christmas or not and what it comes down to on a business level is Christmas is being exploited for profit and not being celebrated for what it's true meaning is.
When "Merry Christmas" is negated from the season, it is being said that Christmas is irrelevant and the season made popular because of Christmas is lost and it will become a season of commerce generated by the lost memory of the birth of Christ.
It's a popular and financially lucrative time of the year because of the birth of Christ, not because it is an expected and required financial spike to the economy.
I say this pragmatically, not in a religious way.
