The tone implications are not an objective fact. They are a quirk of your social group.
As I wrote above, I'm "aware" of the implication in that I have seen it described many times. But it's not an implication that actually exists in any context I am part of.
By contrast, the belief that the ordinary smile emoji U+14642 constitutes an insult rather than a smile is a very real, and therefore more painful and annoying, part of my personal context.
