Should C osmopolitan be covered up on newsstands, just like porn rags? Absolutely, according to the National Center on Sexual Exploitation , which has pushed for the magazine to be sold behind blinders because of salacious cover content. As WWD reported today, the group says it has gotten stores owned by Rite Aid and Delhaize America - the latter runs East Coast supermarket chains Food Lion and Hannaford Stores - to agree to cover up the magazine.
