I answered the following answer to How can I ask an unfamiliar coworker to eat more quietly?
Explaining to the asker that what he wants is not possible is perfectly fine on SE Is "Don't do it" a valid answer? This is not a controversial topic/post, the question is on topic and I didn't write anything rude.
My answer is similar to the first part of https://interpersonal.stackexchange.com/a/2765/5412 which is highly upvoted and accepted. If what's missing is "As a human being, I'd be offended if..." I can add that. I don't have something comparable to the second part of that answer because I don't think it exists.
If you think that my answer is bad you should downvote not delete What do we delete, and what not?
General guidance as far as I've seen is that bad answers are downvoted, not deleted - Catija ♦
