***Edit:*** Rather than ask why my comment was deleted, I’d rather ask, ***was it not useful?*** 

I understand moderator fatigue is real, and comments are noisy — especially in Workplace — but, for a while, my lone comment seemed to usefully support an [answer on a controversial subject](https://workplace.stackexchange.com/a/128212/44698). I also understand that “ephemeral comments” reasoning is more of a [handy moderator tool](https://meta.stackoverflow.com/questions/380262/why-not-delete-all-comments-after-a-time) than an actual thing, because they are never truly deleted.

I chose to comment in support of the answer which, I thought, said it better than I could, and I wanted to signal to others that I thought it was a better answer than the more upvoted one. My comment, which was by itself for a time, was “swept up,” but I think perhaps without consideration — though not maliciously — because:

1. It seemed useful to me
2. It wasn’t violating any policies
3. There weren’t many noisy comments on that to begin with (that I saw)

***Now*** I do understand that my comment may not have been useful to one or several moderators, but, if so, I’d like to hear that harsh-ish but honest answer rather than one which — perhaps — dismisses my concerns (and caused me quite a bit of confusion and frustration).

***Previous question***

I commented on [this answer here](https://workplace.stackexchange.com/a/128212/44698), which was part of a [HNQ about last week](https://workplace.meta.stackexchange.com/q/5934/44698), itself in response to [another HNQ,](https://workplace.stackexchange.com/q/128198/44698) and was supportive without being conversational, and was not a “thank you” comment or extended discussion.

I thought that my comment:

1. Added to the conversation
2. Provided support as an alternative perspective
3. Was polite, non-aggressive
4. Not inviting of nor replying to a conversation

In fact, it was the ONLY comment on the answer for a while. So there was by no means any conversation, extended or otherwise.

What was the rationale for deleting my non-violating, polite comment on an answer which, frankly, hasn’t had many comments anyway?
