Edit: I just learned from a comment on another post here that it's literally the only rule for this community. Thanks @db0@lemmy.dbzer0.com for taking out the trash.
I just ran into several comments all saying this. If you're going to be policing this community for "normal human behavior" you've certainly got a lot of work cut out for yourself. Almost everything about ADHD is an exaggeration of normal human behavior, we don't randomly tweet like birds or wear silly hats, it's the exaggeration that makes it a disorder.
It's also really invalidating and it's the same gaslighting crap that we've had fed to us by jerks our whole lives.
It's also hard to verify whether they actually have OCD or not, since OCD lies not only on a spectrum, but also differs in terms of the subjects being obsessive compulsive over.
I myself am lucky to only have a mild form of OCD that I had to learn to live with throughout my younger years. My OCD fixations are 1. having to do something an even number of times (can't just have one dumpling or three, gotta have two or four; can't just click my mouse like a normal person, gotta find some empty space to do another click to even it out, or spam it till my lizard brain is satisfied) and 2. having to go back the way I came (even if it meant walking a longer route), and if I don't satisfy those, I get extremely anxious.
Those fixations were quite severe when I was young and it got me into a lot of trouble. Over the years, though, I've managed to suppress most of it and learn ways to deal with the rest, and I am very grateful to even be able to do that. Seeing other people living with their OCD is a humbling experience.
(To be clear, I've never been diagnosed. I come from a culture that basically tells you to suck it up and deal with it, and "mental illness" just basically meant "insane" to my people, so me saying what I have is OCD is based off of personal experience and a bunch of self-research; it might even just be a different mental disorder, like how Jon Richardson found out his "OCD" was actually OCPD, but I don't know for sure. I'm not worried, though.)
