Please read the story at the link, but, the long and short of it is that Zero is forbidding GS and contract priests from ministering to their flock, even if they volunteer to do this for free. They risk being arrested if they attempt to do so.
This would be, what I would consider an unlawful order. Were I still in uniform, I would disregard this egregious affront to Christianity, the Constitution, and the people in uniform today.
Zero needs checked for mental defect. Only a maniacal lunatic would take such actions. It is true, that many of the rights and protections civilian citizens enjoy do not apply to our service members. However, the right to worship has always been sacrosanct, with the only exceptions being if it conflicted with duties or harmed readiness and unit cohesiveness.
