Trapped, I have nothing at all against you but I feel I must respond to what you have had to say about my remarks on roscoe. It is not a question of taking pleasure in the misfortune of others, as you put it. It is a question of quality control. If this forum comes to be unduly populated with nonsense, then the knowledgeable posters, and those who come here genuinely seeking a better understanding of science, will simply walk away, thinking it is just another forum for cranks. By "nonsense", I do not mean discussion about unconventional or personal theories, provided this is reasoned and mutually responsive - a proper discussion, in other words. What I mean by nonsense is threads in which one or more posters fail entirely to engage with the arguments put forward in response, and simply keep reasserting their notions. Sometimes this even goes so far as to create new threads repeatedly on the same subject. Worst of all, there are people (trolls) who take perverse pleasure in simply annoying people. For a good example of this, look at the thread from GaiaGirl95 on spontaneous combustion, or the one from river, a couple of months ago (in chemistry), on the understanding of water. In both cases, the initiator of the thread conducted a policy of being deliberately obtuse, in order to prolong the discussion and exasperate the people responding. You should not be surprised if people such as myself express relief when such individuals receive a ban. When they do, is is not a "misfortune" as you put it. It is amply deserved and a great service to the rest of us. I make no judgment at all about you, as I have had no intellectual interaction with you. And I'm not looking for a fight with anyone. But I do detest being taken for a ride by people, when I have gone to the trouble of trying to explain something as well as I can, and I am quite prepared to name names when I feel this has taken place.
