I stumbled upon this post and I’ve been twisting my head back and forth trying to absorb and understand this. I haven’t had much time to really sort it out but something tells me it’s worth knowing about. While I’m putting this on my personal back-burner, maybe this speaks to someone more immediately and maybe someone will make it clearer to me before I start digging.
