That might be true if we were dogs, but we are people and so we have a culture. Culture reflects our experience, not just as individuals, but as a class. People here talk about getting mixed up about individual experience and class experience all the time and yet mix this up.
Goosefoot I was talking about gender, so I don't know what dogs have got to do with this, since they only have a sex. My whole point is that 'gender' is the socially and culturally constructed stereotypes around sex. Unpicking where 'sex' ends and 'gender' begins is important if we are going to be talking about the same thing. But 'culture' is not one thing - it varies from place to place and over time, which means 'gender' varies, but sex does not.
In terms of definitions, I am using 'sex' to mean anything which is connected to the sexed body either directly or indirectly. Anything which has been arbitrarily assigned to one sex or the other is 'gender'. By (my) definition, 'gender' doesn't include those things which can only be done by one sex or the other by virtue of what sort of body they have, or those things which are necessary for one sex or the other.
But I would point out first that you are not correct that gender only refers to arbitrary cultural ideas associated with sex anyway.
Is there an agreed definition of 'gender' which states this? Because the definition of gender as I am using it is that it is about arbitrary cultural ideas.
Look at something like customs and regulations around sex segregated spaces. Those are not identical to sex, they are constructed sets of customs and values we associate with sex, and they could be entirely different.
But sex segregated spaces are to do with differently sexed bodies, so in my categorisation, they are nothing to do with gender, they are there because of sex.
You could consider something arbitrary though, like clothing style or hair style.
This idea that somehow people will cease to care or notice if we get rid of these kinds of customary associations - does anyone really believe that? Or think that people would even go along with that? It would require as mush authoritarian discipline as the harshest and most prescriptive of gender norms.
Why do we have to 'get rid of' these associations? They can be less rigid, so that anyone can wear anything, without forcing anything on anyone. In the same way as only about 100 years ago it was unusual and unacceptable for a woman to wear trousers, and now they are a standard item of women's clothing. The meaning of 'gender' changes over time.
And we will associate certain things with the two sexes, like motherhood, and all its associations, probably the most primal association of womanhood even though not all women are mothers, because we all have a mother.
Pregnancy, giving birth and breastfeeding are the preserve of women because a requirement is to be of the female sex, but all the other functions involved in bringing up children can be carried out by anyone, it is only gender which suggests that child rearing is a woman's job.
This may be going a bit off topic for this thread - or maybe not, since the Quakers seem to be as confused as anyone about the difference between sex and gender.
