That’s not the definition of mansplaining as explained to me by so many women I’ve discussed it with. What you define in the first paragraph is just run-of-the-mill condescending behavior. Frankly, I’ve seen as much of that from women in the workplace as from men. I was under the impression that “mansplaining” is when a man attempts to explain something to a woman that is specific to a woman’s experience (thus, a man wouldn’t know, e.g., advice on how to be a working mother) or talks down to her because she is a woman despite being more qualified in a given area (applicable to the tech article story you recount.)

If we’re going to insist on using this term, we really all need to agree on a actual, focused definition. And if it’s as broad as the second sentence states, then it’s not needed and applies to everyone, and even worse, opens us up to annoying instances where women who don’t want to deal with being disagreed with wrongly accuse others of mansplaining.
