Woman wears Muslim headscarf in uniform. Cites religious freedom.

Just a thought... I have to take down my "Have a blessed day" sign from my office cubicle at my government job because it inappropriately exposes others to my religious beliefs, implies a government establishment of religion and conflicts with the mythical "separation of church and state" proviso.  What if those same people are forced to be exposed to her Muslim faith by having to interact with her in her head covering, in uniform, in the execution of her government duties?  Where is the Freedom From Religion pack-o-wolves?  Why are they not petitioning the DOD to have this woman's religious beliefs driven underground?
