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.

Tony Brooks, Is this true ?
Try to enforce that one.
If we can’t say Christmas, and say Merry Christmas, then things are getting pretty bad in our own country. I will always say Merry Christmas and celebrate the birth of our Jesus Christ. This is suppose to be a free country and freedom of speech. MERRY Christmas everyone!!!!!!!
To ALL YOU LIBERALS and Democrats… Don’t worry this STILL does not classify him as a DICTATOR. He’s still the same patriotic American, God fearing Democrat that you voted for (TWICE!). YOU BETTER READ YOUR CONSTITUTION and do ALL you can to preserve it.
