I'm saying "It depends." My experience with that behavior indicates that it's usually counterproductive- either nitpicking like my previous example, or axe grinding that isn't really helping. Think an Ayn Rand follower interrupting a class on Marxism every few moments. The problem, really, is that it's impossible to make a fully qualified statement and still be engaging. As a speaker, you have to skip over some detail somewhere, thus there is always going to be a place to jump in and act an ass.
