Would you please explain the math example? I was in school until last year (Germany tho) but I don't get it (the 4chan argument about percentages and races?)
The steelman argument for the subjectivity of math would be something like: the process of choosing how to represent/model a real world situation in mathematical terms may influence what conclusions can or will be reached under that model, because biased assumptions can sneak their way into the model.
To be clear, this is good knowledge and should be taught.
However, it is not an effective attack on the coherence of natural number arithmetic. We have to get students to a certain level of objective operational competence before they are ready to think about the subjectivity of mathematical modeling.
