Addressing this is something that was tried recently, with mixed results.
Over the last few months, various members of the community have spent a great deal of time discussing and refining the rules for questions and answers on this site.
One of the proposed ideas was to try to encourage that questions be phrased to ask for a particular denominational or doctrinal view. That's partly why there are questions like "What do Catholics say about..." or "How do Baptists view..."
While that did a lot to clean up the truly awful posts on the site, it did limit the questions a bit, and the price was that it was quite de-motivating. From my perspective, the primary issue that this caused was that you needed to have a more than passing understanding of Christianity to even ask a decent question. The standard actively prevented "seekers" from asking questions, and drove people away that may have gained some benefit from the site.
I don't know if the moderators are still actively pushing this, but it seems to have settled down a bit. There seems to be a line between allowing "sloppy" questions and over-regulating the questions. Finding the line has been a battle for the moderators and the community. In my opinion, the site is now where it needs to be on that line.
While I think that your concern is valid, I'd be hesitant to address it in the form of changing standards for the site, or making an official stance on it simply because I think it would push us back to the "too rigid" side of the line, and would discourage participation.
I think a better approach would be to use the following approaches, based on the question:
- Be sure you're phrasing your own answers as you'd like to see them phrased (which I'm sure you are)
- Post opposing doctrinal answers, taking time again to phrase them as you'd like to see them phrased - specifying the doctrinal view from which the answer derives.
- Gentle, polite, helpful comments on answers that are valid from a doctrinal stance, but speak as if they are speaking for everyone. There's nothing wrong with a comment like "This is a perfectly valid answer from the Armenian point of view, but not all Christians would agree... The Calvinist view states..."
- One of the best things I see moderators do on this site is post helpful comments and include phrases like "this could be a perfectly acceptable answer if..."
- Use the power of the down-vote.
- Not everyone cares, but some do.
- I personally hate voting people down without leaving a comment about why, because I see a down-vote as an opportunity to learn. Simply voting someone down doesn't teach them anything, but voting them down with a comment can.
- That said, comments aren't required when down-voting. I'm just saying they're helpful.
