About 20 or 30 years ago, I would have agreed with this statement.
However, world wide, as Christmas has made its way into predominantly Asian cultures (Japanese, Hindu, even into China) people do not instantly think of Christ first...
For the Japanese, it is more like a romantic day of whimsy and gift giving. A friend there told me of a Santa in the nativity holding the effigy of the Christ child... they do not understand it as they are predominantly Buddhist or Shinto and only mimic a lot of what they see coming out of the US or on TV. Even in the big cities (like Tokyo) the religious-ness of the holiday is utterly misplaced... in some places I've seen pictures of the nativity with Mr. & Mrs. Claus presenting the Christ child with toys... in others you got the crucifix but with a happy snowman instead of Christ. The most "interesting" of traditions is the Christmas (or Santa) Chapel "Love Hotel"... (mentioned in this blog:

The Chinese, not many of which are christian (less than 1% of the entire population), do indeed celebrate the day - Santa and trees and lights and what not, but again, it is more of a decoration thing to appeal to the westeners (and again to emmulate) than it is to celebrate the birth of Christ. They are also (in recent years) becomming more commercialized, so shopping and gift giving is becoming rather popular (my Chinese programmer sent me a HUGE wall plaque of my Chinese Astrological sign. His card read: "For celebration in Christmas Holiday your monkey!")

In India, where christianity is also the minority (2.3% of the population), the day is celebrated with singing and gift giving, but in different ways depending on where you are in the country. What is most common in the decoration is the image of a white man in a red suit... with or without the beard. The city of Bombay has the largest christian (catholic) population, and there it is most traditional, but still a minority celebration.
The reason I highlight these three countries is they have the largest and most influential populations on the planet (next to the US). When you ask people from these countries what they first think of when asked about Christmas, first is Santa, then is presents (but in Japan is KFC and Christmas Chicken). Only when pressed will they respond with, "Oh, and is the birthday of the (American or European) god."
I do programming projects with people from all over the world... and the most questions I get (outside from clarification of software requirements) is about Santa...
"How does Santa get presents to the children?"
"Will Santa always give coal - or maybe dung to really bad people?"
"If I put Santa on my roof, will he skip my house?"
"What kind of gift are you hoping to get from Santa?"
... and onward...
These coming from ADULTS mind you! I was simply amazed that people 30+ in other countries actually think a real person named Santa will visit them and leave gifts! When I explain what Christmas is and about, then direct them to websites... its like telling a 4 year old that Santa doesn't exist... and the magic leaves their lives.
When further explaining that the holiday is actually a celebration of Jesus Christ's birth, they get a little upset with me... and say they'd rather wish I never told them that.... for now they have a fundamental issue as they feel their own faith and customs are being challenged and taken over by the whites. I calm them down by saying the Easter Rabbit is real and will bring them jellybeans in the spring!
Interestingly enough... seems what the ancient christains did (by absorbing local customs or even replacing them for whatever purpose) is still in practice today....

Okay... I'm done waxing intellectual. I go back to being barbar paladin wanting to run events....
