Because these areas are part of the nuance that allows SF-like mentalities to exist. Ignoring that nuance ignores the larger problem on how these bubbles can happen.
I really can't make any sense of this. Is it supposed to make sense? How can something be part of a nuance? What is the nuance you're talking about? And if ignoring the nuance means ignoring the "larger problem," how is it that it is a nuance at all? Is nuance just supposed to be a word for something you don't care to explain?
To me, 'nuance' is just a word to describe "the sub-surface stuff that has no immediate and apparent effect within a local system." So, when I say "ignoring the nuance ignores the larger problem", I'm suggesting that there's a large set of problems occurs when you ignore the lon-local effects - ideologically and physically.
It's a complicated problem with many, many components. Nuance is more relevant than you think it is. Think of fractals and weather patterns.
