I don't know why the rest of YC is downvoting and claiming this isn't the case. If you search previous Theranos threads, you will find questionable comments extrapolating a blanket view on women in tech.
In my experience, people often have a (completely understandable and human) selective view of downvoting and flagging activity. There's a wide variety of opinions and perspectives on HN and I've seen all of them downvoted or flagged at one time or another, just as I've seen commenters of all persuasions be civil, well-reasoned, and, unfortunately, egregiously trollish and ranty.
It's also the result of being around highly technocentric where we've erroneously optimized for logic as the driver in all debates. Unfortunately, dialectics aren't very popular.
For example, I regularly see transphobic statements that simply go undownvoted/unflagged on HN. I was even downvoted for adding Chelsea Manning, a transgender whistleblower, had full rights to be the correct gender because it was a human right.
Ever since Trump got elected, I find HN picked up a bit of intolerance.
