Right here we have a high level meeting with a bunch of competent White Men debating the correct course of action. None of them are in fear of insulting their superiors. The concept that they could be fired or, as demonstrated in the next movie but NOT in this movie, killed for failing their duties, was totally outside of their understanding. They were "traditional" in that they could debate freely, as Men, without repercussion.
That's how White Men determine the best course of action. Everybody has a voice, then everyone decides (voots) on which idea is best. Or just as often, as here, everyone vigorously debates their position then immediately supports whichever decision the leader makes.
CS Lewis covered that in the Narnia series. Prince Caspian, I think. One of the animals is appalled by the stupidity of an idea and voices his opposition vocally and without restraint. Then the Prince chooses that same plan, and the animal becomes the most vigorous to enact it. Why? Because his Prince made a decision, and it was now his duty to obey.
That's visible in that one scene in Star Wars. Even Darth Vader is obedient when commanded to Stop Bickering by his superior.
What did The Rebels do? "I am not a committee!"
