It is her opinion, and it is hyperbole. But the gist of it I get. The sexist attitudes toward women in male dominated areas, from fraternities to sports to the military, are well known, and often these attitudes generate "rapey" behavior, if not outright rape.

From her description he seems to have that kind of attitude, including calling women "chicks".

But as she states in her article, she kept to herself. There is no indication that she share this point of view with him, and more indication that she did not. She specifically stated he knows nothing about her.

In that same paragraph she talked about his innapropriate and unprofessional behavior. If you had any sympathy for what it might be like being a woman, you might be a little more forgiving of her hyperbole, and less forgiving of his calling women "chicks". You might have been taken aback that he went to the manager because he felt "uncomfortable", pointing out that the person who is most justified in feeling uncomfortable was her.
