Absolutely this. A normal range of feeling / experience isn't a "bit of a disorder" ... it is no disorder. Feeling like you need to wash dirt off your hands before eating isn't a "bit of OCD", that's normal. Worrying irrationally so much about clean hands that it ruins your life, leaving you crying from normal tasks like cooking ... every touch of a surface triggers fight/flight ... is a disorder. It isn't the mechanism that's important, but the impact and motivators. Same with ADHD. A bit of being inattentive or forgetful or whatever ... isn't a "bit" of the disorder that also contains some of those behaviours in extreme.
