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.

SAY MERRY CHRISTMAS ANYWAY! SAY IT IN HIS FACE! HE’S A LITTLE MUSLIM COWARD ANYWAY!
What is he going to do next? Where is our freedom of speech and religion . If God is for us. Who can be against us? Obama is going to hell unless he repents and ask God for forgiveness . I am sure he is the antichrist.
Timothy John Brown O can go to hell, grab guns and defend your county!!! Deport his army!
That is a violation of the 1st Amendment !!! This man already knew that, he studied the constitution while in college !!!
He can’t stop freedom of speech or religion
Tell the military to say Merry Christmas all they want. This guy is going back where he came from in a few short months. Hurrah!
