By the commenter, you must be referring to yourself.

Over half of the working age disabled were employed before the passing of the ADA and that number went down after the passing of the ADA. Seeing as being employed often (but not always) involves going into public, and is a key measure of integration with the public, I'd say the disabled were far from "pretty much" not going anywhere in public before passing of the ADA.

In fact one could argue the ADA harmed integration in public of the disabled by the side effect that it lowered their employment.
