Do I understand correctly that you believe it is okay to refer to a woman as a "bitch" in the workplace (and startups should actively screen for people who feel otherwise)?
This is not a rhetorical question, I'm just taking your suggestion to "read carefully" very seriously indeed, because right now it seems to me you are making a statement about yourself you may regret later.
No, you don't understand correctly. Did you not read the distinction I've made several times here about a joke uttered at a conference and calling a woman a bitch on the job? No, I don't think the latter is acceptable at all. And the screening I referred to is not for potential sexual harrassment claims, which I BTW take very seriously (my wife is a professional)-- it's for people, male and female, who are professionally and continually aggrieved. Regrets? Not on HN. Karma is like that.
Did Noah know the word Bitch would set her off? How about other words which are commonplace, which would she feel insulted by? We don't know. And I think it is for this added uncertainty to a team that he was referring to rather than the specific term "bitch" which is, of course, commonly considered offensive in a workplace, particularly in direct reference to a known individual.
What's the problem with calling someone who is being a bitch a bitch? I call people who are being sniveling weasels sniveling weasels. Some people are just bitches, and it's not even restricted to people with a certain chromosome makeup.
