> People keep focusing on Pao's gender, but IMHO the main reason Pao was not liked in reddit is not her gender or race, but rather that she was too old for the role. Plus her business background was not really exciting.

Grasping at straws. She was met with a massive, organised campaign of hatred. This isn't explained by being "old" or having a "poor business background".

But being a 1) female, 2) asian person who had 3) recently lost a highly-publicised gender discrimination lawsuit and 4) enacted an anti-harassment policy would explain the hatred. There is a large number of people who are misogynist, racist and/or openly hostile to what they view as "political correctness". And a much larger number of people who will listen to and possibly be pursuaded their lies.
