Don't. You were right to call them out. Like you said, the sticky keys accessibility feature is turned off by default and must be manually activated. Most of the people commenting in this thread didn't know it existed until now.

Besides, disabled people can't just go out and buy new shit every time they need to overcome society's lack of empathy. 20% of disabled Americans live below the poverty line -- i.e. they cannot afford basic necessities like food, shelter, water, clothing, utilities. They're twice as likely to be poor compared to "normal" Americans.
