I'm not asking you to take them at face value, I'm asking you simply to consider them at all without immediately jumping to possible alternative explanations of the same set of facts that are a lot more complicated than the original one, that she claims that she was harassed and then ignored and that was the end of it.
Occam's razor and all that.
Harassment does happen, and in cases like this the person that steps up has enough problems on their hand without being dealt more crap.
The prior situation has no bearing on what she claims happened, it either did or it did not, and even if it did not the complaint should have been taken serious.
So we're not even getting to 'taking the complaints at face value', we're simply establishing that she claims that her complaints were ignored. That's a pretty low bar to have to jump over, if someone claims sexual harassment and you ignore them then you're simply wrong, regardless of whether or not the complaint is true.
