The respondent could approach it by denying the premise and presenting data
Moreover, you still haven't articulated what premise must be conceded in order to complete the assignment.
In the case of this story, the respondent did deny the premise, they just happened to reject in a way the instructor found personally offensive.
...and how does one construct a wordy essay for a rebuff of a conceptual idea in the realm of the soft sciences?
Rejecting an idea in the hard sciences can be done with data, the soft sciences, not as much...it becomes like trying to prove a negative.
For instance, if it were virology, and someone was pushing the idea that one could kill covid with some random supplement, one could point to clinical trials, case studies, and experiments proving the assertion is incorrect.
The "gender norms are just stereotypes and are oppressive" isn't a testable theory that can be proven or disproven through repeatable experiments.
In other words, it's a non-falsifiable theory, and like with many other theories in the soft sciences (and to a certain degree in economics as well)
- it relies on vague concepts that can't be independently measured
- defined broadly enough that it can accommodate contradictory outcomes
- structured in a way antithetical information can be leveraged as "further evidence of why my theory is correct"
For example: if someone were to say "look at how many independent societies emerged with the similar sex-driven roles and sex-driven task assignment, that would point to this being more of an outgrowth of organic pattern recognition about what works and what doesn't", and their response being "see, that shows just how deeply embedded these constructs and stereotypes are"
