These airmen did not do this alone, they where ORDERED by someone to do this if the word God was mentioned, this goes way up the chain of command. Follow it.
As I see it;
The ceremony was probably supposed to be a silent display (only music in the background, no words)
A man in civvies stands up and a uniform IMMEDIATELY stands beside/behind him ... and seems to be telling him to sit down
Until the civvies start to speak
The civvies started out describing "Our flag" and describes color etc
Three front row uniforms stand up and one is told to stand down .. a fourth (now three total) joins and the civvies is forced off the stage
ONLY THEN OFF CAMERA, IS THERE ANY MENTION OF CHRIST (NOT GOD)
I conclude there was an invitation to speak and a copy was requested
The copy was submitted
The speech was rejected for language and an offer to allow the speech without certain language
The civvies refused
The speech was allowed but the men in the room were alerted
IN A WAY ... this was staged
"...who, being themselves but fallible and uninspired men, have assumed dominion over the faith of others, setting up their own opinions and modes of thinking as the only true and infallible, and as such endeavoring to impose them on others, hath established and maintained false religions over the greatest part of the world, and through all time;...that it is time enough for the rightful purposes of civil government, for its officers to interfere when principles break out into overt acts against peace and good order; and finally, that truth is great and will prevail if left to herself, that she is the proper and sufficient antagonist to error, and has nothing to fear from the conflict, unless by human interposition disarmed of her natural weapons, free argument and debate, errors ceasing to be dangerous when it is permitted freely to contradict them.
