I think you're kind of presenting a good argument for learning to shoot in Auto mode rather than P mode; or someone who shoots in P mode like its auto mode.
The thing is P mode lets you change settings, its whole concept is more like and advanced auto mode with a user control element. The thing is in order to be able to use P mode to its best effect you've got to be able to have some understanding of what those different numbers which are changing actually mean. Otherwise they'd be safer just fun shooting in auto mode because otherwise they are just going to get confused as to how the changing numbers are affecting their photos.
As for people on the forum being encouraged into learning the basics, I think that is the right direction to take. Whilst there is a good argument for letting people grow on their own and settle into camera shooting I think that its something that doesn't really work well with distance learning. With distance learning anyone who comes to the site with the intent of learning is going to already be at the stage where, in their mind, they want to be out of auto or P mode. They want to be a "photographer" or at least understand a little more about it. Pointing them in the direction of resources to give them the very fundamentals of control is the right method for the beginner. You can have all the artistic eye and talent in the world; but if you can't use the tools of your craft it won't do you any good.
Yes this does mean discussions for beginners focus upon the technical aspects of photography more than the artistic; that's because its where a beginner needs to start their focus early on. Once they've grasped those fundamental basics of camera control then they are in a position where they can start to commit those methods to long term memory and (through time) they'll be come the instinctive part of shooting. Letting them then focus more readily upon the compositional elements without having to worry about the random nature of leaving the camera in charge of the settings for the shot.
Now I can say that there is a distinct lack of discussion on advanced and even quite basic compositional elements on the site as well as artistic instruction and foundation. Sadly its a bit of a black area when it comes to many because a lot of people don't have any artistic training and many also give it a very romantic aspect in the "there are no rules/theories/fundamentals its all just random fuzzy thoughts that just happen" kind of approach. Indeed some people can get quite aggressive if its suggested that there is a technical and structured side to learning the craft of art itself.
The other aspect is that many people often don't quite come back to learn the art side; they get good at the technical and don't often push themselves as strongly to really learn the artistic side beyond picking up on the good old "rule of thirds" aspect as well as maybe one or two others like a basic idea of leading lines or repeating patterns.
So yes I'm one of those who says lets learn those basic technical aspects - it is the path I took and I do think its the right path to make. Not just because its the path I took, but because; when starting to learn photography, that is where you need to start. Its like drawing - if you want to learn to draw you've got to put the time into not mastering art first, but mastering the pencil - drawing repeat examples, copying, learning how to hold the pencil etc..... all those dull "not creative" technical aspects that are often as dull as watching paint dry. But once you've learnt them - once you've got those basics then you can build up from them.
Of course life is not just a single pathway and I'd always encourage people to dip into learning some art elements early on as well - just don't let it be the focus first. One primary focus at a time until its more instinctive then shift the primary focus.
