I don’t have enough reputation to vote to close or migrate questions, so instead I commented on this question and wrote “This question is about math, not physics.” The comment was deleted. Was it wrong, rude, or otherwise inappropriate for me to write this comment?
3$\begingroup$ I don't see any deleted comment from you on that question, nor do you have a deleted comment like that on any other question. $\endgroup$– ACuriousMind ModJan 13 at 22:33
$\begingroup$ I understand 100% of all physics that don't require math. Which is about as useless as your comment was. $\endgroup$– MazuraJan 27 at 1:51
The user posted essentially the same question twice, presumably by accident, then (correctly) deleted one of them. Your comment was on the other, nearly-identical question. (However, you will not currently be able to see anything by following that link—since you have to have 10k reputation to see deleted questions.)
