When writing this letter, I aimed to explore the reasons for using stereotypes in the media, and the negative impacts they have on the society. In order to be able to analyze both sides of an argument, I decided to include both sides of the argument. The letter is addressed to an editor of Gucci magazine, which I believe is a company that sexualized women in their advertisements, voicing an opinion I would expect from the general public regarding using stereotypes in marketing. At the end of the letter, I explore the reasons behind the usage of sexualization of women, and misconceptions made regarding stereotypes and their effects on the society by predicting what the reply from an editor would be.
