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?

Transition, I guess. The Vietnamese society generally do not discriminate against transgenders. I’m not sure about Western societies. But I live in Vietnam, so it is the scope that I care about.

We can accept transgender because we know that, after having transitioned, they cannot fake their feeling and gender identity to sexually harass people of different sex.

The subject I was talking about was not specifically transgender, but the “72 genders”. I generally accept that a man can transition into a woman and vice versa, but that still 2. If we add intersex people and people who are unfortunately lack features of either sex, that would be 4. But this number 4 refers to biological sex, it doesn’t match 72 genders.

that’s not being uncomfortable with “fickleness” that’s drifting into bigotry territory.

The “fickleness” refers to [“I feel like a woman” today but next week telling you “I feel like a man”]. I don’t think my society will ever accept that a person can identify as different genders in different time of days, even if we accept transgender.
