Revolution is a team sport. For all players to carry out their assigned roles, they must be able to work smoothly as cohesive units. Lacking this, there is no hope for Victory, since division will do the enemy’s work for them.
As the Golden Rule says, “Treat others like how you would like to be treated.” Even if you’re not religious, I’m sure the secular wisdom of that will seep into your cranium eventually. Almost nobody likes being stepped on or pushed around. If you think about it, collectives of any kind are irrelevant in this context, given that what is at stake are the interpersonal relationships of individuals.
While your individuality is superior to any notion of the collective, you must balance your needs and wants against those of other individuals for the sake of everyone’s liberties. Airing your neighbor’s dirty laundry allegedly for the sake of what you misconceive of as “the truth” is anything but diplomatic, especially if it is handled in the absolutely worst way possible. Cyclical infighting is proof positive that the factions involved do not possess the leadership capabilities needed to perform even basic tasks, much less conduct a revolution; they deserve to be ostracized, since you don’t need their taint on your reputation. Diplomacy is all about you taking responsibility for your actions and their effects upon other people.
Snitching is an excellent way to burn political alliances, intelligence contacts, and business associates. Neither is it diplomatic to whine about your own childhood or the child-rearing behavior of other people’s parents; render aid if you must, but do not cause a scene. Managing a business or organization of any kind requires leadership, and that is only developed once you have your social skills finely in tune with the prejudices and expectations of the people you must interact with regularly. Self-control and discretion are the hallmark traits of the diplomat, and can be evidenced by what is not said, but perhaps implied.
I am not suggesting that you must altruistically sacrifice your values upon the altar of social cohesion; what I am saying is that you should balance your own desires against that of your compatriots. If someone made an off-hand comment that he intended to be a “joke,” it would not be wise to tell him that he is being rude; however, if a Kool-Aid drinker is accusing someone else of being a government agent, then that would be the time to stand up for the innocent fellow and call the bluff of the “guess what I know” type. Being sensitive to what is truly important is what provides for true social stability.
