Christy, the deaf girl from S6 Amazon made it all the way to the F6 despite her handicap. The reason she was ultimately voted out was because she felt too secure being a swing vote for the two alliances remaining in the game, but was punished for her indecision. So she was voted out not because of her handicap, but because she was too wishy-washy.Even if she committed to one of the alliances and made it to the Finals, sitting next to Jenna M. or Rob C. I don't believe she wins..."sympathy votes" or not. If she sat next to Matt she would have won, but not because of her handicap...but because Matt was a wackadoodle.
Ultimately the final decision rests not with Production, CBS, or MB but with the castaways themselves. The is Survivor 21. Kelly B. was keenly aware of what she was getting into, yet she still applied, went through the interview process, endured the two-week sequester the fianlists are subjected too, and probably signed on more dotted lines than President Obama during a 4-year Presidential term.
The only way I would personally have a problem with it is if special provisions were made or the show changed its format in some way to cater to a handicap and/or conviction of a particular casted player. To my knowledge I don't believe CS or MB did that with Kelly B., so it's all good IMO.
