First of all, when someone's conduct has crossed all the tidy little lines of the agreement: (1) disruptive conduct; (2) polite warning given, which specifies the conduct in question; (3) persistence in the disruptive conduct; he can be quite properly called a troll. He is entitled to none of the protections of the agreement. We treat the troll as we ourselves would expect to be treated. It's the Golden Rule being applied to someone that everyone realizes is breaking all standards of civilized behavior in here.
What's happeining here is that someone has been labeled a troll from another thread, and here we are in a new thread, and the same person is here. We don't need to go through the same drill each time a new thread is begun.
If only one or two on the creationist side are able to see anything wrong with the troll's disruptive conduct, it's because they have not yet awakened to the serpent in their own garden.
