These people are not real military fans, but they really don't have any knowledge and skills in other fields. They can only rely on relatively unpopular knowledge (such as military or other relatively uncommon knowledge far away from daily life) to establish a poor sense of superiority. Such people must not communicate with them. You can't learn anything from them, they are just the objects of negative emotions. Moreover, the average age of these people is very low, and the biggest one is usually only college students. More middle school students have never experienced social beatings and simply don't know how to behave. Before the rise of the Internet, such commodities existed in large quantities. With the Internet, their negative effects were amplified. Real military fans are too busy studying their hobbies to engage in cyber violence.
