T.V. hosts can say whatever they want. We live in a country that values freedom of speech. However, television programs depend on popularity, and advertisers to keep them in business. If you offend half of the audience or people at home, they will stop watching your show, and they won't buy the products that the program advertises, so the money will stop supporting the program. If people complain, they will "boycott" the soap, soda, cars, or advertised products, and the program will go off the air for lack of money. Also, if a program or show host gives his opinion on his values, (such as agreeing with, or not agreeing with homosexuality, certain races, certain religion, abortion, or other debatable ideas) and you offend certain groups of people, those people will boycott the advertisers, or publicly speak against the program, and the program will lose part of the audience. To stay in business and make lots of money, you cannot offend people or try to sway ideas or religion on anyone. However, some programs do this, and they have enough support and listeners that they remain popular with enough people to "stay on the air". The Chinese lady trying to be hired by a program was probably "tested" to see if her ideas would be a good fit with the television program's viewpoints, and if the advertisers would approve of her. If a public personality (person) does not say things and agree with the producer, they certainly won't be hired.

I think media impacts culture and culture shows up all through media. This is a constant issue where one changes the other and it is not one way.
