Who's proselytizing?

The refusal of the chief chaplain of the Air Force to support a program promoting political correctness at the Academy is being held up as a violation of the separation of church and state (which IMHO is not a true Constitutional doctrine). The problem is that the producer of the program is essentially proselyting Christians for the view that they're the only ones who are intolerant, and should ignore Christ's commandments that they should declare his message. Others might not like it, but if it is done without rancor or demeaning of other beliefs, as a testimony and not an argument, it should be protected speech under the Constitution.
