ADHD is one of the most well-researched disorders, and medication is very effective. Removing the "disorder" label would only lead to people not getting the help they need. In Europe it is already an awful situation with psychiatrists completely ignoring your symptoms or using outdated information for diagnosis such as not being able to sit still or say the days of the week backwards (I shit you not, that was a hard requirement that exempted me from diagnosis).

For some reason, neurotypicals really want to normalize our disorder so that we can be exempted from proper medication and treatment because we're just like them but just a little quirky. It makes me very angry to think that instead of just giving people medication, one of the most effective treatments, they'd rather just employ "accommodations" that nobody is going to care about properly implementing, if they even barely help at all.
