You really are dense. No one is saying “the class is the same as the gametes”. A sex is indeed a phenotype - but defined by a gamete type. And you know this. You dishonest clown.
You cannot answer the classification question unless you can properly define the classes. You refuse to do the second to make the first look problematic.
We agree being transgender has no objective meaning. It is a social fashion. We disagree about why people call themselves transgender though. In adult men, it is a fig leaf over a fetish.

Your definition allowed me to think a bishop was a gender. So to avoid that you hand arbitrarily altered your definition to exclude “titles”. Witt about “arsenal supporter”. Is that a gender too?
That is gobbledegook. If I am a bishop, I will have such perceived notions of self based on the social obligations of being a bishop. Is a bishop a gender? If not, please tighten your definition.
What is a gender? Can you use your own words to say what a gender is? I doubt that. Can you give an example of a gender and say what defines that gender?
