Amusing that you think they'd take a suggestion contrary to their belief on how things should be done. Every forum and discussion is 'us and them', just varying degrees of hostility in how it's applied, heh.
Most level headed people will examine a suggestion that goes against their belief of a system, be it dialogue or whatever and may then take certain elements they like the sound of and add their own twist to it. Hence leading to innovation or to a lesser degree some sort of evolution of their original belief. They may still reject it, but if it is potrayed in a better light without the elements of 'us and them' it's more likely to be noticed and taken account of.
Even the Catholic church changed the 'Holy Ghost' to the 'Holy Spirit', changes to systems or beliefs that are apparently cast in stone are not unheard of.
Maybe I'm just naive, I don't know. But the majority of posters here are intelligent and that intelligence can be put to better use than being hostile, thus rendering their ideas unnoticed.
EDIT- The whole point of my last couple of posts, is that there isn't that clear of a dividing line between people that is being put forward here. Every person has their own unique opinion and there is common ground to be found there.
