Groups like the Freedom From Religion Foundation are actively trying everything they can do to remove or replace Christians from public life. These are very angry people who rage against the thought of anything Christian passing in front of their view. So they sling lawsuits against people who have Constitutional rights to freedom of religion. And they also have been trying to remove or replace chaplains in the military.
Thank you, Navy, for rejecting the idea of a secular humanist chaplain. That would be an oxymoron. Or perhaps just a moron. Anyway, logic prevailed this time.
