Critics of targeted marketing strategies argue that this practice is discriminatory and unfair, especially if such a strategy encourages a group of people to buy a product that may be injurious to them or that they cannot afford. For example, community leaders in largely minority neighborhoods have staged protests against billboards promoting beer or cigarettes in these areas. However, the Association of National Advertisers argues that banning targeted marketing constitutes censorship and thus is a violation of the First Amendment. What are your views regarding this issue?
