Unfortunately, I know very few prog fans who use those words to describe it.
To be fair, of course no prog fan is going to describe it that way. All of us think we're better than everyone else at something, but we'd be fairly socially inept to go around actually saying it out loud to everyone.
I don't think social ineptitude has anything to do with it. I'm pretty socially inept, but I also won't go around making an ass of myself by making wide-eyed claims such as, "my music is better than yours because we play in 99/64 time and have 49 minute epics." Though, I've met enough people like that to understand why people mock prog fans. I think it's more about making others feel inferior or maybe it's an insecurity issue with themselves. I guess you could put that under the umbrella of social ineptitude if you really wanted to debate it, but when I think social ineptitude, I think of someone like myself who has terrible social anxiety and is fully introverted and tends to avoid most social gatherings.
To me, I find it to be a more interesting genre because of how some of the musicians try and explore new territory. It could be the most simplest piece of music, but something so beautiful and endearing. Vinny from Anathema said it best. He doesn't understand why so many bands call themselves progressive bands when they essentially make the same music over and over.
I'd rather listen to something different, if it's good of course. I've probably tried to explore more new prog bands than most people here, so I can unequivocally say there's a lot of crap out there. Prog does not always equal good or mind-blowing or even complex.
