This book is pornographic in nature. Walmart and Target have long been known to require music albums they sell to be censored, even going as far as refusing to sell a product if no edited version was available.
Fifty Shades Of Grey is a text book example of pornography and making these products available to children (Target keeps them in the 'young adult' section) is contrary to their own practices and against the best interest of the community as a whole.
This petition is not opposed to the sale of the book, this is opposing the open sale of the book to minors. This book should be treated as pornography. So Walmart & Target should discontinue selling the book. Either that, or start selling pornography in general if the dollars they'll make are worth more than the standards of our society.
