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.

Well I will always say Merry Christmas. No matter what.
purebs right wing propaganda
No body listens or pays any attention to anything that idiot says or does.
Surprised?
Hell no! Our miltary men and women ALSO have their First Amendment rights! In fact, that is one the rights they fight to the death for. This dicktaor has no authority to make that kind of a ban on their freedom of speech. Get this Commie out of the Whitehouse, and let him dangle on a tree for all the treason he has committed against the United States of America.
Now he is thought police?
