Honestly, I liked the term a lot when I heard it. With competition like 'learning disability' and 'a bit on the spectrum', it was like a breath of fresh air. If it makes people who don't have ADHD less likely to bully kids at school, then it may be worth the inaccuracy.
Plus, it hits the point that you can't make broad assumptions about people with ADHD. Some people need medication/ therapy. Some people have coping strategies that reduce or eliminate the need for either. A lot of people are still trying to figure things out.
