What's an "S" world? Or an "N" world for that matter? This forum segregates the divide much more than the real world ever does.
You are right, of course. But do bear in mind that this forum is built upon a foundation of discussion and intellectual stimulation. An analogy- suppose S were to be represented by white, and N by black. You could argue that the world isn't black or white, but shades of grey- and you would be completely correct.
That doesn't, however, inherently invalidate discussion about the differences between black and white. The fact is, even in a chromatic world, some shades of grey are closer to black than others and some shades are closer to white- and if you observe that the world seems to be predominantly, say, light grey- then surely that is something that can be pondered about, and discussed.
The division is, of course, emphasized for the sake of discussion. You could do the same for the rich/poor divide, male/female divide, divisions based on religion, ethnicity... the list goes on.
Everybody should realise that you can never define an entire person based on one of their qualities, the same way you can never predict the movement of a solitary particle. But just as large quantities of randomly-moving particles may exhibit patterns (be they representing solid, liquid, gas or what-have-you), large quantities of complex people who share a particular quality may exhibit behavioral patterns as well. You might go so far as to imagine someone saying (perhaps half in-jest) "What's a solid, liquid, or gas? You people segregate the divide much more than the real world ever does," and they would be completely right.
That said, divisions for divisions' sake are pointless, and it's up to each individual (and perhaps all of us together as a community) to decide how much is useful and how much is not. Different people have different levels of interest and/or tolerance for this sort of thing. I for one, personally find it quite fascinating.
