Self DX/Diagnose also has consequences

I think it is time discussion needs to happen why not only self DX/Diagnose is BS or wrong, it also has consequences as well. The reason for this is that people who find out it's a ok to self diagnose themselves with autism usually find out employment opportunities become limited and in the past I have referred people who self dx to a psychiatrist to assess and certify that do not have autism and one of the people who I referred to became very angry at me after they were assessed and certified that they did not have autism, the psychiatrist assessed them for FDIS (Factitious disorder imposed on self)/Munchausens and they met the threshold for FDIS, not only that they became very angry and when I mentioned to the person that self dx has consequences and they should be responsible for their own actions
