Well, I'm Black and survived lots of trauma and child abuse, which admittedly colors my opinion but here's a run down:

ODD (or Oppositional Defiant Disorder) is a diagnosis almost solely given to Black and Native/Indigenous American kids (and its often given to Black/Native/Indigenous kids who display the same symptoms that get their white counterparts diagnosis' like PTSD, Autism and ADHD).

The symptoms of ODD largely revolve around "disliking authority figures", "being angry", "defies rules and authority figures", and "argumentative". I think like, 50% of kids in prison get diagnosed with it in the US.

Its not used to help kids, its used to label them as "bad" for displaying feelings and things that are often explicit signs of trauma and/or neurodivergence, especially kids of color!

The "science" (or lack thereof) behind it has been torn down repeatedly and yet the DSM-5 continues to keep it there so people can use the diagnosis to fuck kids over. And its not just the racism that pisses me off, to be clear!!
