“Grownups never understand anything by themselves, and it is tiresome for children to be always and forever explaining things to them”
- Antoine de Saint-Exupery, The Little Prince
That would be removing information and strictly worse that including it.
Communication is about communicating information, sometimes a terse short and aggressive style is the most effective way. It activates neurons in a way a paragraph of polite argumentation doesn't.
the contention of your respondents and downvoters is that regardless of your intention, the extra information actually communicated is "i'm an asshole".
More accurately in the context of the comment, its "Im gonna be an asshole to you because I think you don't have the life experience I do", which is at least, some kind of signal.
“More effective” at what? No one is ever going to be convinced by an argument that begins with an insult. So what do you mean by it will be more effective?
Do you honestly think an insult never brought about a change in a person? You never think a carefully landed and accurate insult made someone reconsider their position?
Weird, because in my experience, that has happened to every single person I know and myself. Whether it's at the start or end of a comment is not really the point.
Maybe you'd prefer if we were all maximally polite drones but that's not how humans are, going back to GPs point, and I don't think it's a state than anyone truly wants either.
