Yes, unfortunately i think you’ve missed a few things.

1. Anyone can be sued for anything, whether the suit is successful depends on validity and damages
2. It would be difficult to prove damages in this case, but you don’t need to sue anyone anyway
3. Only businesses and organisations serving the public are required to follow the ADA
4. The government, if it received enough
   valid complaints and received a negative reply from a place which needs to follow the ADA might consider bringing legal action or enforcing penalties
5. Common practise does not exclude the possibility that something discriminates against people, which is why these rules were written

I think that about covers it

And miss out on the reminder that my existence is precarious and dependent on the good-will of the able-bodied? Nah, that’s head-in-sand stuff. I prefer to remind everyone of what this line of questioning has led to in the past and the human consequences of discussing the rights of a group of people in the abstract.

Oh cool, it’s time to find out how much of a burden on humanity I am and whether I should have been left to die. Just hypothetically of course, I wouldn’t want anyone to misunderstand. I always enjoy this question with my morning coffee.
