To publicly display your submission and pledge loyalty. If a new ruler can make the masses kowtow before him, theyre less likely to fight him because by kowtowing theyve already admitted defeat. People are less likely to do something if they publicly vowed not to do it, for example cheating in a relationship or abandoning a partner after you publicly married her, or lying after swearing on a bible before giving a testimony in court of law, because you want to avoid being ostracized for being a liar. In marketing and persuasion, it is called the "yes ladder": If you can get people on board with a small agreement or small commitment, they’ll be more likely to follow you to a bigger commitment. Saying out loud the pledge of allegiance hundreds of times as a school kid makes it harder to say no when the ZOG finaly asks you make yourself available to the meat grinder. Acknowledging the Holohoax makes it harder to refuse to "help" Jews. Kids accepting "gifts" or becoming "friends" with fags makes it harder to resist when they try to molest them. The list of examples is endless.
