I bielieve it is sick to put people with real mental and physical illness on tv. I do not suggest it is gross,I do know it to be normal, but the simple fact of putting people, who have no real idea of consequence or society, on tv for others to make fun of.
If i had a son who had these sort of disabilities or illness i would not let him on tv for the public to ridicule and judge. For the people who enjoy this show: From the bottom of my heart... I believe you are sick in the head and draw happiness from others grief and hardship, don't try to mask it with "i think it's heartwarming" because behind every nice person there is 5 bad and that is the harsh reality of it.
It's just one of those things you should see in life, on the street, and not on tv as a show.
