Assuming that everybody has something worth listening to makes a huge, fallacious assumption that simply causes you undue suffering. People use words to inform. People also use words to manipulate and gain power over someone. Recognize the difference. You will feel much better and be a much more effective communicator.
Just because the only way you understand discussion is in order to share information and discuss things logically, someone else may just use words to try and twist your mind, use whatever dirty tactic to gain an advantage over you, or over a group. They don't care about logic, they don't care about information, they don't care about fairness. Only thing in their mind is power. Recognize.
