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.

[Hello71]

the contention of your respondents and downvoters is that regardless of your intention, the extra information actually communicated is "i'm an asshole".

Fine, that's still extra information.

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.

I wasn't the original responder btw.
