I did not vote, but I can understand it - because of your first sentence already: > So the diagram should not be used because of an education problem with some audiences? You dismiss the problem of education as if that is free - but information is physical and spreading it takes significant amounts of time and energy, brains are what they are and hard to change, so this is so obviously a very significant problem that I don't see a basis for discussion given the context here. A forum such as this is a bad place to talk about very basic assumptions, to be able to have a useful discussion about topics such as this some minimum common understanding needs to be there. Accepting the reality of how people think and behave is rational. To answer your rhetorical question: Yes! That reason is valid. We usually only have less than a hundred comments that are useful, many more and most won't ever even see them. If we had to discuss such basics, it would be a huge waste of time, and it would be detrimental to the overall value of the discussion. That includes explaining it to the commenter. I think it is okay to make such comments less visible. In my view it's less about "punishment" or about annoying the writer, but about letting the other people concentrate on other comments that don't force one into side-tracked discussions about very basic things. I would suggest that you don't take it personal, we all occasionally are in that same boat.
