'she argued that gendered behaviour and interests are not necessarily something we should seek to abolish?'
The problem is that so many behaviours, preferences, abilities etc are adhered to and imposed on one sex or another.
Embedded in society, imposed from birth, massively reinforced, and with enforcement constantly, from generally unnoticed, to extreme.
The things themselves generally are not an issue.
Eg
Everyone is more or less emotional, expresses their emotion in different ways etc.
Currently society (sex role IE gender role) says eg
Boys are more logical than emotional. Rational rather than driven by feelings.
Boys don't cry.
Women's emotions often cloud their reason.
Etc.
The problem is not whether you are someone who cries more or less readily, or the varying degrees of emotional reaction to certain things, or that different people think and react in a variety of different ways, and differently to different things.
It's that the reactions etc that humans can have are divvied up between men are like this and women are like that.
When in fact of course plenty of men cry some at the drop of a hat, and plenty of women don't very to much at all.
Everyone is different. Take away the insistence that it's men this women that, let everyone be as they are.
Ditto clothes, interests, everything.
The behaviours etc don't need to go. The boxes do.
(Bar things pressed onto society that are not helpful for anyone, whatever their sex).
