Well, but surely the posts are fully emotional, right? The point is not that the facts behind the emotion are meaningless, it's the orientation of the discussion.
Of course one can reach a destination by heading in the opposite direction, because earth is round; but it would be awfully wasteful.
One can also influence people and make things happen by being super emotional/ideological, in other words, being with super little rationality (not that they are incapable, they just orient in that direction naturally). But that would be awfully ineffective.
