I tend to have the same reactions to the "why?" question and it is much harder when I'm not face to face with the questioner. I have found that after the third time answering and/or clarifying the same question, I'm done. Either I suck at explaining myself or the person really doesn't want the answer and it's all about forcing me to justify my thoughts or behavior. In either case, there is no good reason to continue any discussion.
The real kicker is when the questioner finishes the "discussion" with a deliberate misinterpretation of my response to them. That's someone I'll never talk to again because I know they're just jacking with me and trying to keep me on the hook.
The unfortunate outcome of dealing with those kinds of people is that it makes me less likely to answer the "why?" question from someone who sincerely wants to know.
