It’s not criticizing disability rights. They way hyperboles work is that they need to be over the top. If you want to use a hyperbole for terrible news about America, you need something terrible that specifically wouldn’t happen, even in America right now. That’s why they used disability rights - because they’re NOT in danger. If they had said something like “America revokes gay rights” it wouldn’t be a hyperbole, because that’s a real risk at the moment.
