If you need use of specific words, slogans, clothing, implements, secrets handshakes, or silly walks to be a member of a club, then it's probably a cult.

Grifters in various media markets have done a very good job on behalf of their respective backers and establishment to divide and conquer and manufacture consent of the audience into atomized disorganization with the above arbitrary elements and almost arbitrary wedge issues that that might be a first step in reevaluating a belief structure. The next might be a bit of introspection and consideration of other people's perspectives.

Stay unsure, curious, and calm.
