Gender diversity is all about people being different and special. Sometimes some people feel like they are not the same as everyone else when it comes to being a boy or a girl or something else.
Now imagine if all the people you knew looked and acted the same. It would be really boring, right? It's the same for gender. It's good that some people feel different because it means that we can learn from them and have new and interesting experiences.
So, it's okay if someone identifies as male, female, non-binary, or anything else. We should accept and love them just the way they are because everyone is unique, and that's what makes the world so cool!
