Free speech fights are when people disagree about the right to express their opinions in public. For example, some people may want to tell others what they think about a certain topic, but someone else might not want them to do that. Free speech fights happen when both sides have different opinions about whether someone should be allowed to say something or not. To understand why this is important, think of it like this: everyone has the right to express their thoughts and opinions without fear of being punished. So if somebody tells you that you can't say something, it can be a free speech fight because they are trying to take away your right to speak freely.
