I'm not the one who started this discussion on what touch typing means, I've just given my view on it. Perhaps I could've phrased it more softly, but I won't deny it's what I think. And again, I agree with your assertion, but only when specificity is actually required. Otherwise, if you're going to claim, outside of those contexts, that touch typing only refers to a specific technique, then yes, I think you are being pedantic.

EDIT: Since I replied to your initial comment, I'll update this one too. There definitely is some confusion with regard to your analogy. The point I was trying to make is that while Taekwondo is a type of martial art, it has different styles. From my point of view, you think only a specific style meets the definition of Taekwondo, and all others are something else entirely. If I were to choose a different name, I'd say something like 10-finger, or the home row technique. But I'm not going to try and force you to use any term other than what you want to use. I just have my own opinion on when it's appropriate to be strict and precise in its definition.
