If we had better workplace protections or stronger unions in the US it would be a different story, but it's hard, given that there's no realistically practical way to prove your offer was rescinded because you're in a protected class. I've started disclosing disability before the written offer only because employers are such pricks when they get the revelation after the fact, but I know I've lost offers because of it and if I weren't economically privileged I wouldn't do that.
