Yeah; 'mansplaining' in that context is the perfect word for what the head of the dev team in my previous company used to do to me; he'd call a meeting of everyone senior involved in the project, in which he would explain to me, slowly and with small words, what problems the new release would cause for the documentation and what complicated setup he saw as the only solution, and refusing to let me (the actual technical writer) interrupt until the end. At which point, after like ten solid minutes of him talking, I'd say something like 'We have all those terms set up as variables, I changed them yesterday, and we're good to go. Was there anything else?'

And that dev head was a raging misogynist.

I'd be a lot happier if there was a different word for it, though. While, to be fair, it's a behaviour I've primarily encountered from men, it does rather tar the entire gender with the same brush. Anyone got any better ideas? :)
