What I should do if answer is clearly wrong, and this is corrected by a suggested edit? Reject or accept? As I understand we cannot change sense of post by editing. But a wrong answer is a worst thing for me.
- The mistake is likely due to a typo or some other obviously inadvertent error and is corrected by the edit.
In all other cases, e.g.:
- The wrong (version of a) definition was applied;
- The wrong implication is proved;
- A theorem's hypotheses were not fulfilled,
my stance is that the edit should be rejected because the meaning of the post is changed in such a way that only the author could do this.
In these situations, instead of an edit, comments, and possibly downvotes, are in order (but please take the time to write a comment). One should also consider posting one's own (corrected) answer, with attribution to the wrong answer if this is due in some way.
