It's not offensive for you to post accounts of your married life, or abuse, obviously. I'm the last person who wants to silence victims of abuse. And I have never once suggested that you imagined the abuse. But some of the things you wrote were really inflammatory, for example saying that autistic people damage NT people.
Hopefully, it's obvious to most people that what I'm upset about is stigmatising autism when it already has a lot of misinformation around it.
Autism is a complex condition which takes many hours to diagnose. I have a diagnosis and so do two of four of my children. Being cold, not empathetic and not liking sex are not specifically anything to do with having autism. My daughter with AS is the kindest, cuddliest little girl you could imagine. From the things you say, I can see that you don't have first hand knowledge of how professionals diagnose autism.
It's very frustrating and hurtful when people assume that we must be cold, unfeeling, etc. And using it as a way to explain away horrible behaviour within a relationship. And it's not the first time I've seen this on MN. Fwiw I think it's quite unprofessional of a therapist to suggest that someone has autism if they've never met them and don't have the qualifications to really know.
I really don't want to be having fights with people on MN but I don't think it's ok to leave ignorance unchallenged- this affects a lot of people.
