> why wouldn't we just look at this and say "this is a normal way for a human being to operate" and refuse to pathologize it

I don't think it's so much about that... it's more that having a label for a common set of behaviors/symptoms can be a shorthand to explain things more succinctly.

Btw, would you say the same thing about clinical depression? Why/why not?

Because ADHD (and other things) can be crippling when it comes to actually getting IRL shit that needs doing... done. "We live in a society" is a meme, but there's actually a lot of stuff that can present non-trivial hurdles for neuro-divergent people IRL ... like filing taxes, going to an unemployment office, etc. etc.

(Also, that's not quite what the drugs do if you have ADHD, but I digress)
