You shouldn't have taken that bait...
It has absolutely nothing to do with what SAU is what so ever.
End of the day "stance" and "fitment" has been occurring since at the very least, the 1980s lets say. Probably earlier but for the sake of the conversation lets just pick that.
In semi-recent times someone(s) has simply put a name to it and tried to create a "lifestyle" around "stance". The very creation of a blog/forum like Stanceworks was promotion and "main-streaming" of it. Then there are the stickers every kid on the block has on his car. Every Tom, Dick & Harry talking about "stance" like it's the new "cvnt".
It was inevitable this current re-naming/branding, and that's exactly all it is, a would become main-stream.
Just like the flat cap/singlet wearing/tattoo'd/pierced monkeys walking around now. 5 years ago there was hardly any, nowadays I walk through the CBD on a Sat night and every 5th person looks like that.
I tell you now there will ALREADY BE muppets in the "scene", I know of a few as it is. It's a fact of life.
End of the day these "stance" kids created nothing. All they did was take someone else's idea and run with it a little harder, lifestyle blog, market it etc etc. They only have themselves to blame for what it has become.
It was always going to turn into something that someone would try and gain from commercially on a much larger scale given the following that's been created by it's own followers. Stupid business not to do so really.
Any culture, lifestyle or hobby will end up with a magazine.
So to finish - Here you go stance kids
