Thanks for telling us you don't have a clue what psychiatric disorders are, because that's what you just announced by claiming ADHD is actually a benefit.
Sure, some people with ADHD are successful despite their condition. Some people who are blind or paralyzed are successful despite their conditions, too. But that should never be the standard against which all people with those conditions are measured. That's ableism.
And if you don't consider psychiatric disorders to be "real" disabilities, then fuck you, plain and simple.
