Please, clarify Answer Deletion privilege clauses

Question

Recently, my answer to this question was deleted by the community:

After Tony Stark was stabbed mortally, Doctor Strange made a bargain with Thanos. He offered Thanos the Time Stone in exchange of life of Tony. So, it was actually Thanos who protected Tony Stark from a mortal wound leaving him with a minor injury which he could heal with a spray.

Deleting answers

When should I vote to delete an answer?

You may vote to delete answers in the following cases:

• The answer is extremely low quality: There is little to no scope for improvement
• The answer doesn't answer the question; it may be a comment or a separate question altogether.
• The answer is not much more than a link to another page. Link only answers are not allowed on Stack Exchange

My answer is by no means:

• a low quality answer. It is perfectly readable with proper spelling and grammar and punctuations. It doesn't have pornographic or bigotry content.

• not an answer. It isn't a spam or comment or a question.

• a link.

I believe this feature exists mainly to clean up posts from new users.

Talking about answer correctedness (which is subjective most of the time; according to me, my answer is correct), isn't down voting tool designed just for that? If you don't agree with an answer, go ahead to downvote it. If you are an asker, don't accept it.

This also isn't consistent. For example, these famous questions have several highly upvoted answers which don't agree with each other:

Could I fake death to stop being Force-choked?

Are all stormtroopers as poor soldiers as the ones in the movies?

How did Dumbledore, or anyone, know Lily had sacrificed herself for Harry?

If Luke Skywalker didn’t want to be found, why did he leave a map?

Should we start deleting incorrect answers? And, who will decide what's incorrect? If it's asker, should we start deleting answers which don't agree with the accepted answer? All this will ruin the site. There's a reason correctness is handled with checkmark, not "delete other" button.

We had a similar consensus before:

Is deleting really wrong answers OK according to the rules?

But, it's about "really wrong answers". The examples are clear. It's a trivia that Nagini wasn't present in the first Harry Potter book. But, my deleted answer here can't be classified as "Really Wrong Answer".

Answer 1

I am not familiar with the film in question but as far as I can tell the answer should not be subject to deletion under the guidelines for the vote to delete privilege.

According to Meta.SE

An answer that is not an answer should be deleted (should be a comment, doesn't answer the question etc...).

Answers that are answers but are factually wrong or are actively bad (say promote SQL Injection) should get downvoted, but not deleted.

The same post is cited elsewhere on Meta.SE, e.g.:

What are the criteria for deletion?

For answers, any post that is not an answer (should be a comment, doesn't answer the question, etc.) should be deleted. Answers that are wrong or that dispense poor advice should be downvoted, not deleted.

_{Community Wiki answer to "How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion?"}

These guidelines apply to posts in the low quality posts review queue as well. Meta.SE has guidelines on how to review low quality posts (e.g. here and here). In general, posts which attempt to answer the question -- even if they are low quality (e.g. unsourced) -- should not be deleted. Only posts which are extremely low quality (i.e. offer absolutely nothing of value to the site, are gibberish, don't attempt to answer the question, etc.) should be deleted.

The guidelines given on Meta.SE apply here on Science Fiction and Fantasy as well. We have previously discussed "When should 20kers vote to delete an answer?" and the answer to that question (which currently has a +9/-1 score) says

Use your best judgment

...

Don't delete in these cases, tho

• Rude or Spam - Flag these. When enough people flag them Mods are notified for further action. If 20k users just delete them... nothing else happens.
• Meh answers - In baseball, a tie goes to the runner. In answers, ties should go to the poster. If you can't come up with a good reason for deletion don't do it. Don't stretch to delete. Downvote bad answers and comment.

That question is linked to "Is deleting really wrong answers OK according to the rules?" and all the positively scored answers instruct or recommend not to delete such answers. The only answer which suggests that there's no "issue" with deleting such an answer currently has a score of -2 and even it notes that

I believe that outright deletion is a no-no whereas arranging a downvote storm is perfectly acceptable.

The reason we do not delete wrong answers is that

A wrong answer, downvoted, also conveys information. It tells you, the visitor: don't do this. This answer is wrong, and if you are lucky the comments tell you why it is wrong.

If we deleted such answers, someone else might make the same mistake.

So instead, we (try to) only delete answers that are not answers (when they are new questions, or comments, or gibberish), or spam, or offensive, etc. We don't delete answers merely because they are incorrect.

Taken together, these sources (as well as the Trusted User privilege help page) indicate that there is some judgment required as to what constitutes an "extremely low quality" post (which is subject to deletion) as opposed to merely a low quality post (which should be downvoted, commented on, and/or edited). The reason your post was judged to be "extremely low quality" by some users seems to be due to the lack of sources (not that it was wrong), which would be a valid reason to vote to delete (though I disagree with that judgment).

Based on some of the comments (now deleted) it is also possible that at least some users voted to delete based on personal dislike of you and/or because you are a high reputation user who should presumably know how to post a high quality answer. I don't know if that's actually the case, but just to remind everyone: Vote for the post, not the user. That's true whether you're voting up or down, voting to close, voting to delete, etc.

Answer 2

I can't see anything in that answer that would qualify for deletion. It's not spam, it's clearly an answer to the question being asked, and there's nothing rude or offensive in it.

I've vote to undelete and so have enough others -- it's been undeleted.

If people want to critique the quality, that's what comments and downvotes are for.

For the rest of the meta question -- we've gone over this conversation so many times I can't even read it again. If you think you are being personally targetted by someone on this site, contact the moderators. If you think the moderators are doing a poor job, contact the CMs. If you think the CMs are doing a poor job, this is the wrong site for you.
