Women aren't as strong as men.
How does this substantiate your assertion? The very notion of any society
valuing or espousing strength, is, of itself, a social construct.
Men aren't as good with children, when compared to women. These roles are pre-defined.
There is absolutely
no empirical evidence out there that supports this ill-founded, conjectural and heavily distorted argument. These roles are absolutely
not predefined. A woman staying at home all day and looking after her child while the men goes off to work is social constructionism at its most patent. To say they're predefined suggests that woman are intrinsically better at caring for children than men are. Again, this is arrant, borderline speculation. It may seem 'predefined' to you, but in actuality, it is a product of hundreds and hundreds of years of sociological evolution, mostly rooted in previous patriarchally hierarchical societies. Moreover, having a 'role' in society is socially constructed - it is a form of social organisation.
You simply can not argue that one thing is biologically constructed while you're discussing the salience of 'roles' in society. It completely contradicts your argument.
Just like why men go off to war or work more physically streneous jobs.
Please, tell me, how is this
NOT a social construct? Are you saying that it is in men's inherent nature to go off to war and work more physically strenuous jobs? War is a product of social conflict. Work and labor are salient component to
social living. These concepts are constructions, not innate to our biological inclinations.
But gender roles, and who we are, is a biological construct
Again, as soon as you start talking about 'roles', you're just being completely inconsistent with your argument. Actually, you're being antithetical to it.
