> We don't say, "I'm just questioning!"
> That's the nuance.
I quite like the substance of this article, but it is important to articulate that this sort of analysis is actually a mistake. If you read that level of intent and nuance into word choice, life is going to be very hard and confusing if you meet someone not in your culture bubble. The article reiterates the thought a few times and it is not a powerful idea.
The real issue that I believe the author wants to get at is actually the follow up to the answer. If the follow up is an attempt at persuasion with question marks on the end of sentences people will sometimes (often, really) get unhappy. If the follow up reveals that the question was a pit trap that leads to moral judgement then they will get unhappy. But there is very little tactical difference between the verbs "ask" and "question".
So I like the point, but it is over-analysing the words. A lot is revealed about intent after the question when we start to learn how it is being processed into words and actions by the questioner and that is where the focus should stay.
