The original argument was that it is uncharitable to claim that Damore was "exactly" fired for pointing out pipeline problems has an impact on closing the gender gap. That's not what he claimed, and it's not why he was fired.
> One way that sexism presents itself is an underappreciation of valuable skills, where traits that are typical of the dominant group are recognized as valuable and marked for advancement instead.
I agree, but Damore positioned the differences in gender abilities as a "Possible non bias cause" and not because of systemic sexism (of or relating to "implicit (unconscious) and explicit biases are holding women
back in tech and leadership").
> "6 foot tall basketball players are at a serious disadvantage in the NBA". This is a clear fact.
This is a bad example because, unlike height in basketball, there is no evidence that dimorphism in humans (size, psychological, hormonal or otherwise) causes any difference in preference or ability in tech culture or software engineering in general.
> There was nothing exclusionary about the memo
You're welcome to that opinion, but many at Google felt otherwise.
> and "othered" is a meaningless term.
The editors at M-W feel otherwise [1] and a one sentence definition is returned by most dictionaries and at least one search engine[2].
> He was fired because his memo caused a PR nightmare, and through no fault of his own.
Again, you're welcome to this opinion but that doesn't change the original claim that he was fired for merely having an opinion about "pipeline" issues affecting the speed at which the gap can be closed. That claim would be uncharitable.
