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:

Only anti Americans disrespect the president of the USA. I think we should sell them the Brooklyn Bridge. They’ll buy it.
That seriously wasn’t necessary
Can this guy just go
I despise Obama, but according to snopes this is a false accusation.

This article is completely false. I would recommend not listening to any posts from this site. They are just trying to sell advertising slots.

It truly is scary to see how many people still exist that will believe anything they read, without question or research, just so long as it fits their worldview. I found this in less than 20 seconds, folks:
