I often see people posting about subjects they lack even te most basic understanding of, like religion or geopolitics. I also see people respond to such posts who display even less understanding of their subject matter. This often leads to heated debates between people who are basically all complete nobodies. They are repeating whatever propaganda they have been fed earlier that day and are under the illusion that their manipulated emotions matter to anybody or contribute to anything positive. If you want to voice your opinion make sure you are not one of these people. Turn off the propaganda for a couple of years and pick up a book or twenty first.
