Thing is; if you're not personally or emotionally invested in a discussion, there's no use taking part (and most don't).
However, when you're personally and/or emotionally invested, reason has a tendency to slip, that's kind of the essence of internet forums.
Being anonymous and being able to act like an ass or lie about virtually anything doesn't help alleviate the situation either I'm afraid.
That said; this site is among the best I know of when it comes to discussion, simply because of the amount of reasonable and level-headed posters it has!
