It was a business conference, not a creche or playground and the norm for such environments IS adults only.
“That's when someone approached me and said, "Would you like to stroll your baby outside? I want people to get the full experience out of this conference.””
A perfectly reasonable request that I’d expect and have even proactively accommodated by stepping outside (vs just towards back of room) if I’d decided to attend with a baby. Author may not have felt her kid was noisy but chances are, the YC staff that approached her had noticed or been informed by other attendees that the noise was at distracting level.
“I’m not naming this woman because I think the problem is bigger than me or her. It's about this tension in the business world right now. To many people, including me, the pandemic showed that it was possible to be a hands-on mom and a hands-on business partner. Others want to maintain the status quo of business and babies as entirely separate. To me, that's ridiculous. To ask me to leave with a quietly cooing baby during a talk that was explicitly about the challenges of being a mother and founder was shocking. I realized then that the monster of systemic barriers to entrepreneurs who are also moms is bigger than I ever realized”.
It would be indeed be foolish to antagonize a YC partner in print over a paper thin argument that’s riddled with holes. Systemic barriers to female entrepreneurs including mothers exist but this wasn’t an instance of that and to suggest otherwise is what’s ridiculous.
