Intolerance is about the only thing I won't tolerate. Of course people will rise in their own defence and trolls know this. That is how they disrupt things, by saying something in such a way that they are sure to get a reaction. When faced with this I tend to get my facts in order and become very clinical (though hopefully not boring - See "Times are always a changin'"). The trolls don't care, they probably won't even read it, but others will and see the trolls for what they are. Remember the old saying, "I may disagree with what you say, but I will defend to the death your right to be wrong." You see, I am not always right either (lol).
