I think that actually Big Brother has countered this quite well, by sticking in Darnell, because it's provided us with two people who usually face this kind of condescending pity in every day circumstances, to balance each other out. You can't say "Michael shouldn't be in there because he's blind" because he has every right to be there, he made the decision to audition for the show and he got it. I think BB producers knew they would face this kind of thing, so they perhaps put Darnell in so that people couldn't say "they've stuck this one guy in, he'll be all alone" as you have two unique people with unique circumstances, so we can see how well they both function in the house. Good luck to them!
