Do you believe that men and women have the same biology? If so, then should we stop segregating sports competitions by gender? What would you think about having a man fight a woman in a UFC octagon?
If you're going to say that physical abilities are not analogous to mental/psychological inclinations, then my next question would be is neuroscience just a pseudoscience? Because the consensus in neuroscience is that "form follows function" and male and female brains are definitely different anatomically speaking (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3969295/).
Also I mean NO offense to anyone. I am genuinely looking for a cogent argument from the people who disagreed with Damore's memo.
Where the memo is dead wrong is where he's trying to justify which gender makes a better software engineer because we don't fucking know. Not only that, we don't even have a real canonical set of metrics that define a software engineer. What we have is a set of business metrics we care to see and both genders have shown equal level of capability against those loosely defined arbitrary business metrics.
Furthermore the memo questions the value of trainings specialized for one gender. That is also wrong because historically and presently the opportunities are not equal for both genders due to biases still present so if we want equal outcomes for both genders then we need to reverse some of the damage done to one of them in the space of availability of opportunities.
