And the way I like to look at it is that we should try to have a good grip on ourselves first, because this is what we can affect ourselves — how you start into a communication will greatly affect the reaction of the others anyways.
Especially in IT it is not rare that the answer to clarifying questions muddies the water even more, because explaining a thing often requires knowledge of other technical concepts.
I work in an educational context nowadays and the people entering my door might be anything between totally clueless and domain experts, and just by looking you won't necessarily notice who is which, so indeed you need to figure this out in a small exchange. Bad communicators would skip that step and talk the same to both beginners and domain experts until they maybe get the clue, but if you're unlucky by that point the communication has already ended.
consider this conversation actually happened, this video is just a recreation of it.

Not all of them are so extreme but the idea is the same.

The details may have not been exactly correct, but the point still stands and your nerd sniping is not useful here, especially with the haughtiness mixed in.
Go alpha somewhere else.
This is more about how communication works. Communicating ideas and intentions is always about shaping the words that leave your mouth in such a way the other side understands the thing you intended them to understand.
Inexperienced communicators will say what makes sense to them and be surprised when someone else in a completely different frame of mind doesn't pull the same meaning from those words. Wanting people to understand you and shaping what you say in such a way they get it is not a bad thing. You would also talk differently to your kid, than say to your co-worker. This requires to a certain degree that you can see things from their perspective. Now surely you could use this for manipulative reasons if you are a soul-less bastard, but that doesn't say anything about about the practise.
