You say "borrowed," I say "sanctified." Whatever the origins of the traditions, however, Christmas in and of itself is a 100%, completely Christian holiday (holy day).
To argue that Christmas is not a strictly Christian holiday is, quite frankly, ludicrous. Were there other holidays on Dec. 25? Yes. That does not in any way make them equivalent to Christmas. Notice the "Christ" in the word. Many non-Christian traditions were adopted, but that still does not make Christmas itself not strictly Christian. I honestly don't see how you can argue that a holiday specifically for celebrating the birth of Christ is in any way not Christian.
Here's an example. If I have a birthday on the same day as someone else, but I'm a few years younger, that does not mean that my birthday is not really my birthday, and that I based it on someone else's.
