I understand what the analogy says, but not what kind of real world situations it applies to.
All applications are kinda left handed, and require some serious bridging (the main purpose was to provoke thought).
Say if you lived in a town/city or whatever and there are 2 or more groups in force. Being a new arrival you ask many people what each one stands for and they all give similar and generally positive responses about a certain group. You become generally confused and continue your investigation on who seems to have the moral high ground. Others join you in your search, and before the end the other groups see you as a threat and attempt to force you to become neutral. The issue would be you already are neutral so you'd have to pick who to go with. In the end your decision is yours alone.
Or take perhaps a (probably self-proclaimed) prophet begins prophesying and you begin to follow the prophet because you agree with them(gender neutral pronoun). Later your beliefs are called into question, and you can see why when they do. The holes in the prophet's teachings seem obvious, but you still agree with the underlying message. Again the decision is yours alone.
Whenever you learn or figure something out and ask others your new beliefs will be called into question after probing. To me the analogy represents our limited and divided perceptions. You don't know if anything is absolute and sooner or later you will face that fact or it'll face you. The analogy was intentionally vague and open to interpretation so as to be universally applicable.
