"Yes, I absolutely am sorry and saddened to have made JL upset. Again, it's been my understanding that while the female partners are great and I'm sure sit in on important decisions, they are primarily YC's accountant and lawyer. If that's not their main role at YC, I and others are mistaken. For the record, I think JL is /great/ and YC would do itself a lot of good to hire other women like her."
Based on my extensive experience with all of them, I would shuffle your words around a bit and suggest a more accurate characterization is:
YC's female partners are great and make and participate in important decisions. Though it is not their main role at YC, two of them have chief responsibility for YC's own finance/accounting/legal needs.
In hiring Kirsty and Carolynn, YC did hire other women like Jessica, at least on the "great-ness" scale.
And I wholeheartedly agree that YC would do itself a lot of good to hire other women like all three of them. Just as it would do itself a lot of good to hire other men like pg, pb, Robert, Trevor, Kevin, Aaron, Geoff and Garry.
But my greater point was that there is generally too much criticism and indignation that are substituting for listening and understanding. Put yourself in the place of PG and YC in having unjustified criticism like you posted directed at them. And maybe take that to heart before you throw stones.
