Your brain is not a democracy.
You get to decide what you believe. You can think things that no one else agrees with. You can also like things no one else likes.
You can and must think for yourself.
For instance:
If someone calls you out for something, it’s important to listen to them, and to think through whether or not you think they are right.
If a teacher or therapist tells you that something is socially inappropriate, it’s important to think through whether or not you agree.
If everyone tells you that a TV show you like is awful, it is still ok for you to decide whether you like it
If everyone tells you that something you like isn’t age appropriate, it’s still ok for you to decide you like it.
Your thoughts and tastes are yours. You are the one who should decide what you like, believe, and spend time doing.
