The Obama administration has directed the military to not allow personnel to say “Christmas”, in spite of the holiday’s status as a federally-recognized holiday.
The reason given by armed forces officials is that not everyone celebrates Christmas and that out of respect for them, military members should refer to Christmas celebrations simply as “holiday”-themed festivities.
This prohibition comes in the context of a wider push for political correctness in society in general and the military in particular, as evidenced by the recent reprimanding of Navy Chaplain Wes Modder for simply discussing religion, as chaplains are wont to do, with military personnel.
See how servicemen have reacted to not being allowed to say Christmas at the link below:

HE IS COMPLETE IDIOT. I will say Merry Christmas and have a tree in my house. Is he going to go to every house and take it down. We have Freedom of Speech and alot of other freedoms according to the Constitution. Something you know nothing about.
Once again, first amendment. The so called libs always go after the first and second amendments. They are not libs, they are communists. Political correctness was a Soviet Union concept. Look where it got them.
I have too see this to believe it.
May God have mercy on your soul. If you have one. The Devil is in your heart.
