Blind people that I have known have a sense of humor. Not once is there "anguish" for a phrase.
I had a paster once who was accident prone. Always with a cast or a bandage. One day, I spotted him on crutches, and told him "You must not live right". He had no anguish, sorry, thought it was funny.
Most people aren't offended by this type of nonsense out of the gate. It usually takes a large body of liberals telling everybody how offended they should be before this stuff becomes an issue.
