Editing is a beautiful thing. It is, however, a square peg and some holes are round.
Editing is good when you can fix grammar or spelling mistakes, format for easier readability, fix a broken link, or otherwise improve on a post.
Editing is bad when you make changes that affect the authors intended meaning, even if you think the wording is better.
Our subject matter varies from some other SE sites. In my experience on Unix.SE, if somebody is factually wrong on some detail in an otherwise good post, those who know better can just edit it, maybe leave a comment so the OP learns, and move on. On Christianity.SE, it's not so easy and we need to take this into account. When somebody holds a view on a matter, even if it is factually wrong, you cannot just edit their mind in hopes of making a better answer.
When a post contains views that you do not think are true (even if they are offensive) you cannot just edit the post to make it better. This won't help change the OP's mind, and it will start an edit war. Only change the content of a post if you are reasonably sure the OP will like your changes. If you even suspect that they will have an objection to your edits, you need to pursue a different line action.
Instead, Comment. Try to make a reasonable explanation for why the facts are wrong, the wording can be improved, or the content is simply not acceptable on the site.
Then Flag. If the content is outright offensive, or if the OP does not prove helpful after commenting, flag it for the moderators to deal with.
You can also downvote. Remember! Don't downvote because you disagree with a view -- but you can downvote if an answer wrongly represents the view it claims to speak for, says a right thing in an offensive way, isn't on topic or any number of other reasons.
Lastly high rep users, please do not approve suggested edits that fall outside these boundaries.
If anybody has other suggestions on how to handle this, please add answers!
TL;DR I am raising an objection to viewpoint-changing edits. The place for dealing with wrong or offensive views just isn't the edit system.
