I am so sick of people interfering with the way other parents should be raising children. Sesame Street pulled the Katy Perry episode because of protesting from parents. Ok obviously these parents do not want their kids seeing any part of the human body...Even breast that are fully covered. Good for them, but do not force your views on others!
Some people actually want to teach there kids that the human body is a beautiful thing and not something to be ashamed of. Nudity does not equal sex. Look at some the greatest painting, sculptures, etc. A large majority are nudes or partial nudes. If that turns you on you have some real problems.
People need take a chill pill if you do not want to you child to see the above simply don't let them view the episode, also do not take them in public since most teens and young people where a lot worse than a semi-low cut dress.
A lot of people have said they do not want their children having a roll model like Katy Perry.Guess what if you raise your children right you will be their roll model not a famous singer!
