One of my answers to a question was "edited" by another user. The "editing" consisted in inserting a hyphen in one of the words I had used, and "replacing" some other words with the identical spellings. What should I do in such circumstances?
If you feel the edit conflicts with your intent and does not improve it in any way, you can roll it back to the pre-edit version of the post.
However, if you find even parts of the edit are helpful, consider re-editing the post to undo whatever changes you don't like while leaving the helpful parts.
