It seems the lion's share of the problem was a founder's psychotic wife, who basically stalked her - which doesn't seem to have anything to do with gender discrimination, and all to do with one person being a nut-job.
Of the other issues she raised:
* Another engineer made a pass at her, got rejected, and didn't handle the rejection will.
* Some girls were hula-hoop dancing, and guys were watching them
The first issue might have been a problem, but if it was at all proportionate to the page-space dedicated to discussing it, it sounds like a fairly minor issue, and one that should really be able to be solved by HR. The second is just, well, petty. Sounds like she'd made up her mind to hate the place by that stage, and was finding fault with every little thing.
