All it would take for me personally to reverse my stance on an employer being a good place for women is a single case in which I reported being sexually harassed and management then took the side of the harasser over me. Because one case is not acceptable, and it's all it takes to turn a workplace into a hostile and unpleasant environment.
That's not to say "oh, if she says something, she must be telling the truth", but the possibility that she is telling the truth is a huge red flag.
