I definitely don't think she's lying about this, but someone with such a strongly-worded bio is definitely more likely to exaggerate or be over-sensitive to perceived sexual harassment. (Think Adria Richards)
When your first response to a claim of harassment is "let's consider the bias of the accuser", it casts doubt on the legitimacy of the claim. I'm not saying we should jump to assuming she is telling the truth, and a real investigation should be followed to determine the legitimacy of the claim.
But regardless of the resulting investigation, I'd rather bias the initial reaction to "thank you for sharing this, sexual harassment is a problem in the workforce", instead of using her Twitter profile to cast doubt on her claim.
It is your place to listen and try to understand the world they live in, those traditional recipients of sexual harassment.
I gave you examples where people can exaggerate quotes.
edit: please drop the attitude...
