i’ve hung around the autism subreddits beforei am a teacher and felt a more personal perspective would give me a better understanding of the actual experience of my students and i noticed this but i want to note that the majority of toxic positivity seems to come from one place parents of autistic children of varying spectrum degrees   and i think even some of this from autistic people can be viewed as coming from parents because the rejection of autism as a negative seems to originate from either a parent who was desperately supportive in the wrong way or desperately upset by the traits of their child i see this also in real life with students   there is a bit of a difference here in that people with adhd usually do not have deficits in communication as severe or debilitating as is found in autism spectrum thus toxic positivity takes over in subreddits where the disabled cannot self-advocate as easily because it is necessary for the comfort of the parent advocates and the children who want to please them but that is just a theory
