(I ask this as someone who mainly asks dnd5e questions, as such I am using terms like DM, RAI in the official D&D capacity)
Whenever I ask a question I get a lot of replies in the vein of "at my table...", "when I dm...", "in games that I've played...", "a common houserule is...", "most dms...", few replies directly referencing the rule, and often none actually quoting the rules.
I understand that the majority of the questions on this site are about giving opinions, but sometimes I am interested in what the rules say instead. I feel very bad telling people that while their well thought out answer is interesting it isn't what I'm looking for. I think other people feel like they are being disrespected and their extensive experience is being dismissed. It would be great to be able to manager poster's expectations so they know, before making a long post, that I may not be looking for that kind of answer.
I usually try to add "I am asking about RAW/RAI" but that isn't enough, answers with neither RAW/RAI justification nor quotes come to the top. Should I be writing "In RAW does XYZ" in the title?
In the same token but slightly different, often people jump straight to DM fiat as an answer, sometimes giving very lengthy recommendations about how a DM can fiat the situation. The DM can overrule everything, it's a given that in dnd the DM can do anything, I don't want to hear that a DM can modify the rules. Meanwhile after a dozen such replies at the bottom, downvoted, is a succinct reply quoting the rules directly.
If there really are no rules, that's fine. If you first explore the rules then talk about how you play/modify them, that's fine too. That is all welcome and interesting information for after the question is answered. What I don't like is immediately throwing out the rules without even saying what they actually are.
"In RAW, without DM fiat, does XYZ" is getting a little clunky. I would love some advice.
To be clear, the kinds of answers I am looking for are: "In this section the rules say [quote], and in this section they say [quote], therefore XYZ. This is also supported by [quote]" I am not looking for answers like: "most DMs play it like this XYZ" or "XYZ (with no justification)"
Perhaps a better question would be: Should the default answer for dnd5e questions be "RAW/RAI", "the dm decides", or "in my opinion", and when is it appropriate to move to non-default answers.
To put forward my own opinion: RAW/RAI should be first (with quotes from the rules), then DM decides (with quotes from the rules/dmg), then opinions (perhaps supported by experience).
EDIT: An example is this thread: By RAW: when attacking while hidden, what does it mean to "give away your location"? The top answers do not quote the rules. Frustratingly I tried to ask them to support their answers with rules, but a mod deleted the comments and told me to post a reply, and I did so with as many rule quotes as I could but it just gets downvote bombed without anyone commenting. As such the top answers are, while interesting, entirely useless to me since they are not supported by the rules.
EDIT2: I came across a great example of the problem in this thread The first few answers assumed that there are no rules and went straight to houserule. One user even said that they thought the question should be closed as "opinion based". However the accepted answer is supposed by a direct quote from the rules explicitly outlining how to handle the situation. I would consider the other answers to be not only offtopic, but dangerous to anyone who comes to SE with the same question. Unfortunately despite being explicit that I wanted RAW people still upvoted these dangerous houserules that were presented as RAW.
A user coming to the site looking for RAW will see the top answer to a question with houserules and may not investigate enough to realise they are not actual rules.
