See my post #30. The key word with these folks is “Freedom FROM, not Freedom OF.”
Agreed...however, if they take the effort to push through representation in the Chaplain Corps, then their philosophy is recognized as a religion. As xzins stated, the purpose of a chaplain is to provide support (implying "spiritual support") to both members of that particular religious confession and to the body of the troops in general.
What I'm trying to get at is that these folks want to have their cake and eat it too. This desire, which has now been legitized, may provide a capability for some push-back...again, if our side is smart.
You may need to re-familiarize yourself with such people as Mikey Weinstein. He has championed the utter removal of all references to Christianity generally throughout the military (and in particular, the USAF) -- and has, throughout the Øbama regime, been very well connected with the brass at the Pentagon.
The point I'm trying to get at is that outfits like Thomas More and the ACLJ should keep their noses to the ground and be ready to quickly work with military members, particularly students at the Service Academies, NCO PME Academies, and the War Colleges, when humanist revisionist histories are taught...or with military members when humanist agendas are pushed through "diversity training" sessions...or in the event that there is some sort of discriminatory conduct during performance reviews...or, even so aggressively as to take up action when somebody has as a copy of a book like "The God Delusion" on their desk at work (since people have been reprimanded for having a Bible on their desk before).
Always before, our battle has been defensive. We insist that we have the "free exercise" right when somebody attempts to take it from us. Now, we finally have the opportunity to take the initiative and go on the offensive: claiming that another religion is being forced on our folks.
This is a truly unique opportunity. I hope we don't miss it.
