It was socially unacceptable long before that. I was sent to the office in the 5th grade (1981) for calling a friend "********". I only remember it because it was the only paddling I ever got in school. Beck then the accepted term was "special".
But, honestly, this thread isn't about any of that. It's about stupid people with no clinical diagnosis. The elderly and mentally ill or handicapped people or special needs people who fall victim to scams are just that.... victims.
My best friend's kid was born with downs syndrome. She is one of my top 15 favorite humans on Earth. If she loves you, you're alright by me. If she doesn't like you, I have no use for you. She can spot a bad human from 100 yards away. Best hugs you'll ever get.
Stupid people, however, get what's coming to 'em.
