"I've spent a week cosplaying as a disabled user. And I hate it"
It is hard to empathise with many disabilities until you have "walked a mile in their shoes". You don't even notice the failure modes.
The idea that people should try, and the emergence of products like the arthritis simulating gloves, and good steps.
When the ADA passed there was (and of course remains) criticism that it only helps a disproportionally few people and if businesses didn't want their custom that was the business' problem. But we all take advantage of many ADA affordances either through transient disability (e.g. breaking a limb) or just life (carrying a large number of packages).
Please don't scorn the author. I personally would not have gone as far. And I learnt something by reading the article.
While to pull only that line out comes off as mocking.
