Celebrated by the school, or by the other students? University is where many things in the mainstream are rebelled against and ridiculed. To be on that list is almost proof that you've got the upper hand in society.
Can you give examples here as well? The devil is in the details, as it were.
I'm not going to defend the sentiment that there is a war against Christians/Christmas, since I don't share that sentiment.
Is there an organized effort in some quarters to limit the influence of Christians/Christmas? Of course. Here are a few links.

In all the anecdotes, the common thread I see is a few people in a position of some power and authority deciding for others how something will be celebrated or discussed or proclaimed. Again, that's not warfare to me, that's more like secular conditioning.
