In my position if I have to interview a woman (or any candidate), I can talk to her with my team present.

Maybe it would be different if I was the CEO hiring for an executive position, and then I would make an exception. But for white boarding? Even if it were 1 on 1, I don't understand the need to have the door shut.

Privacy makes me uncomfortable anytime in a work environment. I like my home life private, but I'm fine having my work place conversations overheard by others.

Yeah, that's the only thing on the list that I thought was weird, that's why I said "most." The closed door meetings in all these sexual misconduct stories were really, really egregious and would be easily avoided.

Everything else is just being professional.

I used to be socially awkward, terribly so, and I was never ever afraid of being in a closed room with a woman, because even at the height of my awkwardness I certainly wouldn't 1) make sexist remarks or jokes, 2) stare at her body or, 3) flirt.

People might've known me as a weirdo who stuttered or referred to Star Trek too much, but no one would ever think of me as inappropriate, simply because I never was, not even close.

Frankly, if the power difference is too great, it's not ethically safe to go into a room alone.

Alone in a room with Putin/Duterte in their homefields, and God knows to what you'd agree. If they coerce you, you might not be believed and, besides, they could have you killed.

Never walk into a room, alone with a dictator.

Or, if you're an 18yo store clerk for American Apparel, never do so w/ the CEO of your company.

And it's unethical to ask a subordinate to expose themselves by joining you, the authority, in such a situation.

... extenuating circumstances aside.
