For the really obnoxious types, patience is easy. Since they are not in a classroom or office with me, there is no stress. I don't have to hold back from walking across the room with a baseball bat. I can just ignore the posts. Not even bother to set them to a formal "ignore" but just go find another post. At worst, the really bad trolls may cause me to have a palm-shaped bruise in the middle of my forehead. But that's OK, I used to work for the government, so by now I have a callous of that shape.
As to "amazing tolerance" - I grew up in a Christian home and learned many life lessons from a tolerant mother who managed to not kick my silly hind-quarters around the house a couple of rounds every so often, even though I probably deserved it. She taught me forgiveness. Even if I no longer follow her faith, I recognize the value in forgiveness.
