While I think Damore was quite wrong, I do also cringe when I hear most of the soundbites. There are very good reasons to criticize what he said, but an unfair summary kind ruins the whole idea of discourse about the memo.
Damore's writing prowess is maybe not the issue exactly, other than it is a symptom of the lack of clarity of his ideas. Unclear ideas, unclear writing. It's certainly reasonable to conclude from Damore's memo that what he believes is that "women choose (and succeed at) tech jobs at a lower rate than men because on average they have biological characteristics that mean they tend to be more suitable for other kinds of work" ... preference, biology, culture, expectations, it's all one big interconnected system. He's not at all clear about what, given the biology, he thinks the "natural" rate is... unless he thinks it's already about right? So it's not clear what he means, or even if he knows what he means. Taplin could certainly have been more precise in the NYT, but Damore did nothing to control interpretation of his words (nothing, at least, that succeeded).
To me this is like trying to optimize software in the wrong place. Biology is surely a factor somewhere in the chain, but many other things are causing more problems, and in ways that are easier to fix, so we probably shouldn't spend time on the biology thing just yet, because it won't cause much impact overall.
