I'm 52 now... Probably about 10 or 15 so, I meet my kindergarten teacher (relatively small community) and she told me that she was among the first teachers that allowed children to be left handed.
Definitely have shitty left handed writing and ADHD!
Woah, I've never thought of this and want to see this. Anyone who's left handed but forced to write with their right, who want to write the same sentence twice with either hand and attach a pic?
Alcoholics, Maniacs, Idiots, Shell Shocked, the Insane...
There was this baseline assumption of normality, and then there was this hyper-dramatized lunatic or raving drunk, and you weren't supposed to really notice anyone in between. The idea of a high performing addict or adaptive neurodivergent was nearly non-existent. Two people with ADHD could be staring sideways at a third in disgust, simply because the third wasn't well-socialized or required some amount of assistance to get around.
They had all of it, they just lumped it all in with Down Syndrome and colloquially referred to any neurodivergent people as retards.
And they beat the shit out of these "retards", and at the suggestion of doctors/principals the parents sent them to military school/boarding school/catholic school/mental institutions where they got the shit beat out of them. All they learned was how to hide their condition and suffer in silence.
My personal theory is that the industrial revolution created more neurodivergence. The fact that stuff like computers and trains are common obsessions means that the development of technology is making life more neurodivergent friendly. My grandfather worked for Rolls Royce so I've got tech genes in me.
