I definitely see the humour, but this is necessarily not just a women's thing.
When we as a society increasingly give the power to the offended to decide what is OK and not OK to say, you should not be surprised to find that on average people will be more careful about what and how they communicate, to the point of people imposing self censorship on them selves.
The effect of this on large scale is that because in general people are now exposed to less "hard" speech or statements, they also become mentally less "rugged". Their minds are simply not trained to handle normal discourse or disagreement any more.
And therefore what passes as normal conversation in the rest of the world, is now a fireable offence in Silicon Valley.
And thus people in SV will self censor even more. And become even more sensitive. Rinse and repeat. This kind of stuff is just not healthy. How are you going to we break the cycle?
This episode is going to be a shining example when the conversations return to media bias. CNN, for example, referred to this as a "sexist manifesto" and an "anti-diversity manifesto." Meanwhile the actual memo mostly suggested that if Google wanted to make the company more appealing to women they should offer more part time positions because women tend to choose a different work life balance than men, something that is statistically provable. You could hardly be more benign. I think the right-wing phrase "hate facts" is going to start leaking into the vernacular.
