@Paul1255 I don't think airbnb's policy is very well put together myself.....if you know something that the disabled person requires....like wide doors, strong Internet connection, wheelchair accessible bathroom...is not present in your listing, it seems silly and counter productive to penalize the hosts for being honest that their listing is not a good fit, and then calling that discrimination.
Is it really better to have the disabled person stay as a guest and then have their needs unmet? Isn't it the host who is most familiar with the ins and outs of the listing and whether or how it would meet any special needs of a potential guest, instead of relying on the guest's judgment based on seeing a few photos and maybe or maybe not reading the entire listing?
As an example, we had someone inquire about bringing their 'service dog'. We said, of course you can bring the dog, and it's our understanding that since it is a service dog, trained to assist in a task(s), that the dog will not be left alone in the apartment but will always be with their person. I knew to word things this way because of this forum. And, sure enough, I never heard from this person again, because I'm sure that the 'service dog' was nothing of the kind. But, if I didn't have knowledge of how to phrase things I could have opened myself up either to a scammer or to an accusation.
