Just to clarify, am I correct to assume that "both" refers to me as the second person?Define "least pleasant to others"?
Also, regarding misinformation, there's always the option to argue back. That's the thing though - argue. As in, present arguments. There's always a cause for an effect, and explaining that reason is the point of an argument. "Because I said so" is not an argument, neither is "because somebody else said so and agreed with me."
An "explosion in a manner of unpoliteness and rudeness" is not part of the argumentation process, nor does it contribute in any way, shape or form towards the correction of misinformation nor the "pleasant to others" factor. And yet, you've done just that. Why?
