<p>FWIW, I deliberately have not read the thread in question and therefore have no views here on who is more nearly right, and so forth. </p>

<p>I think this is more general inter-personal etiquette than site policy. </p>

<p>It's OK in my view in most cases to correct small presentation errors in anyone's posts. That is especially easy if you feel you know the other party well in CV terms and there's good mutual regard. (If you're in doubt about that, it doesn't apply.)  </p>

<p>But I would not go there if I was strongly disagreeing with someone technically and/or there was also a history of the person taking criticism badly or otherwise behaving poorly (e.g. a known record of suspensions, angry or bitter exchanges, downvoting etc.). </p>

<p><strong>Any reputation-based right to make edits doesn't over-rule a need to maintain courtesy and sensitivity.</strong> Even minor corrections can be misread as pointed signals (and you can't even spell, punctuate, choose notation carefully, understand basic probability, ...). </p>

<p>The way to disagree, as others are pointing out, is through comments and your own answer (which can cross-refer to other answers you disagree with). </p>

<p>Meta-meta: I edited your question for a minor typo. That was nothing to do with your question or argument.</p>
