No. We do not challenge the premise of a question here - most of the time.
Why?
Parenting is a full-time, real-time, lifetime job. While some other sites encourage or tolerate frame-challenge answers, the subject of parenting is entirely too sensitive for such answers. The nine-year-old boy that is having a certain issue at school is a real, living nine-year-old boy. The parent who is asking for advice on the issue is a real, living, breathing parent who needs our help.
Frame challenge answers increase the content real parents need to wade through to get sound advice. On top of having to find quality answers, with a frame challenge answer, they now are required to defend their position - on the internet - which if the history of open forums everywhere is precedent, it never goes well.
Two extremes are going to potentially be the outcome in the life of a frame-challenge answer. Either the asking and answering party will get into a heated debate in the comment section (which isn't allowed either) and somebody is going to inevitably violate the Be Nice/Code of Conduct policy OR the question asker is going to delete their question, abandon their account, and never visit our site again. Both of these outcomes are clearly undesirable.
I do concede that constructive frame-challenge answers will exist. They probably exist currently on the site in sweet harmony with the rest of the content. They probably exist because they were stated politely, not overly controversial and dismissive, and helpful to the question asker. The frame-challenge answers being addressed are those answers that deviate from that.
So what can I do?
All StackExchange sites are community moderated and community driven. We are given tools to manage and contain bad content and uplift and promote good content. If a question asker is violating the code of conduct, admitting to something criminal, not asking something on topic for the site, or spreading misinformation with their question, flag it for moderator attention and use your powers as a user to vote to close the question.
If the question is poorly written, edit it.
If you just disagree with the general approach the asker is taking about a situation because you were not raised that way, you don't think it will be helpful, or it violates your personal moral code, you have the option to downvote or walk away.
Based on some feedback, specifically from user DXH, there is one more option. Ask in the comments. If you really have a constructive answer that dismisses the premise of the question for a better course of action for the parent, ask in the comments first.
Hey @OP, may I post an answer that challenges the premise of the question? We call those types of answers "frame-challenge answers" here and I was just wondering if you are OK with that?
If they respond positively to that, then go for it. However, if they respond negatively or don't respond at all, don't post it.
What not to do?
Do not get into a heated debate in the comment section. Do not post a frame challenge answers that goes against the premise of the question. We do not do that here unless specifically allowed by the asker.
What if I see a frame challenge answer?
If you see an answer that is a frame challenge, flag it for moderator attention unless the it has been verified the asker is OK with these types of answers.
