Perhaps it would help if you could explain what you understand about Rhansen's post? From your response, I think you missed his point, which is that determining the needs of another is STS. This is quite an important thing to understand - and entails concepts ranging from 'what is asking' to 'self-importance', 'self-referencing' and the 'need to be right' or to be 'seen as a teacher'.
Just because one thinks something is important or should be clarified doesn't mean that it is objectively important or that it should be clarified - but if one thinks only of themselves, of what they think is important and 'true', then this is lost on them - "of course it is important, I thought of it!"
Not everyone wants to know that 1+1 does not equal 5, but if one simply MUST point out the truth to others, then that person is serving themselves much more than others (internal considering)
