Illogical Reasoning

What is the best means to reason with illogic behavior or, even worse, the illogic behavior of a network. Who is to say the reasoning is logical at all and perhaps it is the prsumed illogic network that is completely logical and sane. I'm sure this has happened countless times before. At what point does one cease to care and let their frustration make the decisions or, even worse again, the frustration is directed at others for their less than stellar behavior (in the viewpoint of the frustrated). All I can say is my brother has always managed to find a way to be the center of attention even when his health is failing and those around him have perpetuated and awakened old grudges and suspicions and continued to disagree on what my brother should do, hasn't done, and better do before its too late and whose fault it really is. There is a definite domino effect and a recycling of history in the making if smart decisions are not made soon. Let's hope cooler, and more practical, minds prevail. Just this once.
