The main problem with culture is, in virtually all cases, “you can’t say what they don’t already know.”
Some very small cultures of just a few people are exceptions to this rule, but no large culture with anonymous and/or not-well-known members is.
Cultures demand constant authorization and reauthorization from their members. To stray from established norms is to weaken group authorizations.
In the world today, you cannot escape the above truth about culture. You will find it prevails no matter where you go.
In your private life you can escape the above truth by doing FIML practice. The whole point of FIML is to speak about things you don’t already know.
