Is that what he posted? Do you have some quotes?
Edit: if this is not in fact an accurate representation of what happened, it makes a good example of one of the cons of thinking in public: you may be misinterpreted and/or misrepresented forever after if you reach a large enough audience.
If you're looking for a single "gotcha" quote you don't really find it because the document is a fortress of wordy CYA. I think the only thing to say is normative statements like "women like people and men like things because women are wired to raise children" is post-hoc justification of the roles society prescribe for men and women, not some kind of truth bomb that's too hot to handle. People use similar arguments to the ones in this document to justify differences in pay and representation between races as well. It's a well worn path in sophistry to justify the status quo.
In the interests of fairness, I'll highlight a part of the document I thought was fairly insightful.
> Feminism has made great progress in freeing women from the female gender role, but men are still very much tied to the male gender role. If we, as a society, allow men to be more “feminine,” then the gender gap will shrink[.]
I think framing this as "men becoming feminine" is patronizing and prefer instead "allowing people a greater range of self expression, with men and women able to take on roles and personality traits traditionally reserved for another gender if they choose to (eg, there's no reason to highlight men becoming more feminine and not women becoming more masculine), as well as being afforded the opportunity to adopt non-binary genders previously considered to be invalid." I think it's underappreciated how men's gender role can be stifling and how men and women should both support the cause of feminism to achieve better outcomes for everyone.
I'm looking for any quotes. One thing that confuses the issue is that the gizmodo piece removed citations, which makes it look like this was all his original thoughts. Of course, one response to this is to then attack the cited pieces, but that's a different argument.
Anyways, I'm not here to pick up his banner and run with it. I believe that people did honestly interpret what he wrote as you have here. But I also believe that other people honestly interpreted it as not that.
Which, back to the topic of this thread, is a perfect example of the pitfalls of thinking in public. If people perceive you to be thinking the wrong things about topics that are very sensitive for them, they will react very strongly (understandably).
It's sort of like a variation on murphys law: anything you say publically that could possibly be interepreted negatively will be. And then it needs to be attacked because it might actually move the needle on some issue, whether or not the author intended it to.
