Question: I edited [this question](https://superuser.com/questions/1418589/how-to-store-result-of-commands-to-a-variable-in-batch-file) to remove two misleading tags - the question has nothing to do with either PowerShell or bash. It was rejected twice, once by a subsequent edit by a high-rep user, and once by PeterH, giving a reason of "This edit does not make the post even a little bit easier to read, easier to find, more accurate or more accessible. Changes are either completely superfluous or actively harm readability."

I disagree that the tag removal was superfluous or harmful; if someone were to search for questions tagged bash or powershell, this question would be irrelevant to them, and really should not come up in such a search.

If this rejection was in fact reasonable and valid, may I have an explanation of the policy regarding such tag edits?

Your edit was automatically rejected to the fact it conflicted with another edit proposal. The edit was proposed by a user who can make edits without it going through a review process.

The reason for your edit being rejected wasn't that it was **harmful to readability** but due to the fact it was superfluous due to the fact, no other improvements were made to the question.

The question you modified, is likely going to be closed as a duplicate of an existing question, but it also appears to have several duplicate candidates.
To state the obvious, yes, your edit was OK in itself and normally shouldn't have been rejected.

However, there's one thing you should consider when editing - "is the question / answer worth the effort?" Editing a poor question is a complete waste of both your time and the time of reviewers, because when such post is deleted, your edit will be gone (and so will be the 2 rep points you earn). This would not be case here because duplicate questions normally don't get deleted, but in general you shouldn't be very surprised if your otherwise reasonable edit to an off-topic or nonsensical question is rejected.
