> If a woman quit does that mean it was a sexist workplace?
No. But if she quits because she felt the environment was sexist, then yes.
> If a guy quit after being berated is that different? I don't think so.
Well, male-on-male bullying is also an interesting topic and subject to research, but the topic du jour is sexism, so let's stick to that.
> Also, you linked to a feminist site to provide the definition of a word. Is that normally how people cite the standard/objective meaning of a word...?
Well, I don't know if "sexism" has an "objective" definition, but yes, words are usually best defined by experts on the subjects. Just as gravity is best defined by physicists, sexism is best defined by feminists, who have studied sexism for the past few decades. I'm a newbie to feminism, so I defer to the experts.
> or is this story a chance to talk about something you feel very strongly about whether it fits or not?
It is something I feel strongly about because of this story and others like it. Because so far all evidence suggests that "it fits", I think those trying to make it look irrelevant are suspect.
