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.

I don’t care what Obama says the military should say anything they want to whether it’s merry Christmas happy new year God bless America. Happy Hanukkah or anything that has to do with God. It is their right because it is freedom of speech and the constitution and Obama don’t control either of those two.
You sick Muslim. Going say it anyway! Dare you to take them to court over this if they say it?
No one can tell me that I cannot worship God. And speak the name of my Saviour. I will stand for Christ.
