Hmm, now I'm extremely curious as to what the original name of this thread was.
One thing, your post didn't set a direction for the discussion, it was most definitely a rant. However, like you, I support rants, I think rants are a good thing. If one is capable of keeping good grammar and formatting so as to spare the eyes of the reader from pain, then a rant is the barest, truest form of an opinion anyone is capable of expressing. And one I oftentimes indulge myself in.
However, they make absolutely terrible conversation starters, as a rant, by it's very nature it doesn't have a point, it's an opinion, not a persuasion. So overall they make good answers to topics, but bad introductions to topics.
As far as Escapists not challenging themselves mentally, I think both Emilie Diabolica and yourself have excellent points. You are each partially correct about the population of The Escapist. Some people come here to relax, and some come here to enjoy intellectual discussion, as this is one of the few forums where it occurs with some regularity. Of course I'm saying that from a relative viewpoint. Intellectual debate threads are still rare here, but at least they occur, which is more than I can say for the majority of forums on the internet.
And finally, as for myself, I actually must plead guilty to both extreme physical laziness and extreme mental stimulation. There are times, many times in fact, when I will come across a thread where either the opening topic, or some particular post, or several particular posts, or some combination thereof encites in my a great mental reaction. I will start arguing with them aloud in my brain, if you know what I mean. I will focus entirely on their chain of logic and the faults I see in it, (or at least how my logic contradicts theirs), and will formulate a well-spoken intelligent rant meant to enumerate them of my opinion. Unfortunately, 90% of the time I don't actually type it. You see, I put great energy into it, but it all occurs in my mind, as I can think so much faster than I can type that it feels quite unsatisfactory to do both at the same time and thus slow down my train of thought when I am so impassioned and afterwards, when I have satisfactorily made the rant in my mind (or out loud if it was a subject I cared enough about) I have lost the motivation to make it again in written form. In this sense I see myself as part of the problem you are referring to of people not putting forth enough interesting conversation, though certainly not for the reasons you suspected. However, there is the 10% of the time I do feel it is necessary to post my response and thus, this, and certain other, rants exist on this site by my creation.
By the way, I realize I am backtracking, but on the subject of music, I am capable of enjoying both long well-structured pieces that require attention from the listener to be fully enjoyed, as you are, but I am also perfectly capable of enjoying a shorter, simpler listening experience. There is definitely a lot of skill that goes into composing complex pieces that create anticipation, but surely you can acknowledge that a short piece that is capable of eliciting an immediate emotional reaction from it's listener requires a different sort of skill. There is a ton of really terrible music out there. Music that, for lack of a better term, blows chunks. It may not be the type of music that you're talking about, but I can guarantee that everyone including you, including me, has heard some really bad music at some point in time. Likewise occasionally the bad music will become extremely popular because it's "catchy". (Not all bad music is catchy, not all pop is bad music, but some of it is). The type of people that listen that are the type that truly deserve scorn. But there is plenty of music that is still simple and is simultaneously good. There is nothing wrong with simplicity, as even simple things (such as a particularly well-played 10-second riff) can inspire thought and emotion.
I can't comment on the TV shows as I watch very little television, and the programs I do watch are very really thought-provoking as I primarily watch them to shut down my brain and relax for a while, maybe laugh at some Family Guy slapstick.
On that note, you can't expect people, even the smartest most motivated people, to always constantly be analyzing everything, no one can run on overdrive 24/7, it is medically proven that relaxing is good for your body.
Oh and one last thing, it's a tad condescending to finish your opening post with "but I don't expect any of you to even read it," at least in my opinion.
