Actually, that isn't motivating any of this. What is motivating this (see, e.g., the OP) is a scientific question: what evidence exists that there is any innate difference in mathematical ability based on the presence or absence of a y chromosome? So far, I'd say this thread makes it pretty clear, when you see the data that does exist and how the differences in math aptitude completely disappear when environmental factors are controlled, that there is no significant innate difference. Is that not a perfectly accurate description of every bit of evidence mentioned in this thread that actually related to this issue (and not all the extraneous factors that were brought in to make some phantom case against some imagined influence of political correctness)? The scientific evidence speaks for itself.
