> I'm sure "Mental Disorders" was probably not meant to denigrate the giant chunk of humanity that does suffer from such disorders
The suffering that they have is real, whether or not we debate the appropriateness or usefulness of the labels that have been placed on that suffering. Attempting to shame people for discussing those labels (even extremely negatively) as if the discussion itself damages the sufferers is darkly ironic, because the suppression of the discussion of that distress will result in a failure to improve the treatment of that distress.

edit: I do understand the sentiment, but it's one that has long been cultivated through patients' groups that are founded and funded by pharmaceutical and other medical companies, and push the treatments that their funders push. Their funders are generally deeply invested in the status quo and cast objections to current received wisdom as attacks on the sick, unless they're trying to push a new drug, which is when they push change.
A patients' group can atrophy into an organization with no members, a single funding source, and a lawyer who spends an hour writing a press release every few months, and hires someone to update the website once a year.
