Yes, atypical Brian’s or neurodivergence does not necessarily equal disorder. I hated when my ex used to refer to my “disorder”. I found it not representative and even disrespectful to be honest.
Maybe it’s because we associate disorder with non functioning, when’s it more “life on hard mode in the current social/cultural context”. It also implies there’s something wrong with the individuals rather than recognizing that the environment could also be adjusted to help the individual thrive.
