No, genuinely, you're reading it wrong and taking it personally because others already started the downvote train. Yes what they suggest isn't immediately realistic, but it's easily achievable if people actually wanted to do it.

Like are you under the belief that all of our social structures were borne out of the natural order of the universe - entirely immutable and incapable of change?

Is it truly not possible in your mind that we are arbitrarily subjecting ourselves to unnecessary cruelty for the comfort of people who think change can't happen?

They never said the problem isn't real. They said the way society is structured is what make it manifest as a problem because society is not equipped to accommodate you as you deserve. You don't deserve to be treated as a broken individual, you deserve to not have an unjustly difficult life because of something you were born with. Giving it a negative connotation label as a disorder affects the way people (without a clinical understanding of the word) behave toward you. The label is enhancing the harm you face and would be the first step toward altering the public understanding of ADHD.
