I really do beg to differ. Firstly, players who stir the pot and have alot of drama to them only have two reasons for doing it. Its either they are disloyal to the tribe and they are being coerced by an enemy tribe to sow dissension among the ranks or the guy is loyal and wants the tribe to be in a better shape than it currently is. With what I've gleaned from Change of Heart's and your statements are that he was a loyal member of your tribe, but given that his advice wasn't followed inside the tribe, he was disgruntled and thus turned to this. Then again, I really have no idea with regards to what actually happened inside your tribe, but just from the info here, that is my presumption.
On your second point regarding the externals, its people like you that have led to the death of the externals of most worlds. People who choose to be totally against external representation. Rather than bashing the externals, why don't you just keep the hate to the person who irks you in it?
An example of this was your w14 tribe, WOTB. Metaller was never against the externals, he might have not posted much, but he never did hate the externals. He might have been annoyed at some of the posters, but he never hated the externals. Do not presume to be superior because you just play the game, you should be ashamed that that is the only thing you do.
