I see your point, however, its just a form of entertainment. People watch to be entertained, not to learn morals from these people.
But, by your perspective, watching any form of TV is bad. If you watch any form of sitcom, drama, ect. then you are sinking to thier 'level' of sex, and the other bad things that are portrayed in those types of shows. And they are also candy-coated to look like 'fun'.
Welcome to the board, and hope to have more of your perspective in the future!
