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.
On the other hand, when people mistake any kind of forgetfulness or hyperactivity as ADHD, that hurts both them and people with actual ADHD. Let alone if things like "I fall in love with fictional characters" or "I don't subscribe to gender roles" are suddenly misconstrued as symptoms of a certain condition even though they're just part of the subculture these people move in and have nothing to do with their mind.
Expand to all other mental illnesses or neurodiversities. I personally have falsely diagnosed myself with so many fake disorders when I was younger, and it hurts to see others go down the same path. The brain loves to see patterns that aren't there if prompted.
