Trauma is information. Someone who has experienced violence knows more about violence than someone who has always been safe. Someone who has a disability knows more about disability than someone who has always been able. I think about this whenever big criminal trials are in the news, that they weed out jurors who have been assaulted, violated, attacked, discriminated against, because they can't be "objective" about violence. I don't trust anyone who thinks inexperience is objectivity.
