The difference being, If I was assigned "male" at birth and society categorized me as "boy/man" and treats me as boy/man but I don't "feel" boy/man and would like to be treated as girl/woman, what will that society do?

Somebody talking about a near death experience with God occasionally, probably won't get them lynched, denied housing, proper and dignified medical treatment, the ability to have a romantic relationship, etc.

A society deciding that its weird or uncomfortable to know that a hetero cis gender person marries a person who happens to be transgender, that's not being uncomfortable with "fickleness" that's drifting into bigotry territory.
