If my tone is such that no one engages constructively, then it's not going to be useful whether or not I'm correct. If my tone is such that many people engage constructively, then it may well be useful whether or not I'm correct, as either people learn from my contribution or people (including me) learn from corrections to my contribution. It's more than a little context dependent and YMMV, of course.
