What is one of us meme?

The "One of Us" meme is based on a scene from the 1998 science-fiction movie "Babylon 5." In the scene, a group of telepaths chant "One of us" while welcoming a new member to their group. The meme became popular in online communities as a way to jokingly reference a sense of belonging and exclusivity within a group or community. It is often accompanied by an image or video clip of a group of people or animals, with the caption "One of us" to suggest that the subject is part of that group. The phrase has also been used in debates or arguments to imply that those who do not agree with the speaker are outsiders or do not belong to the same group.
