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.

Wow how bad is this! Shocking!
Let me see. Merry Christian, Merry Christian, Merry Christian. If he does not like it, then leave this country.
Everything is Anti-christ with this president !!!!!!!!
That would be just TOO BAD, if I were in the military…they could kick me out!!!
I would just have to tell Obuma where he could stuff that order!!!
You are an idiot. Go away.
Merry Christmas to all the military and to Christ and God loving people.
