Insults against Islam have long been going on, Muslims have received insults from various quarters since the Prophet Muhammad (pbuh) developed Islamic religion. This situation has dragged on until now and will continue to drag on. Thus, the controversy over the issue of insulting Islam through cartoons or caricatures of the Prophet Muhammad (pbuh) in 2005 through a Danish newspaper is not a new issue. Previously and until now various cartoons painted insulting Islam were spread in many other mass media. Using an analytical descriptive approach, this paper will review the controversy sparked by the production of cartoons of the Prophet Muhammad painted by Kurt Westergaard, a Danish cartoonist at the Jyllands-Posten newspaper. There are two different perspectives in looking at this controversy, the first perspective is the absence of moral elements in ethics that exclude religious sensitivity, the second perspective is also the right to freedom of speech in communication ethics which is based on the ideology of Liberalism. But the motive or purpose for which the cartoons were produced must be hidden the implied agenda that has been devised by the enemies of Islam, especially in the West, given their prejudiced attitude towards the teachings and adherents of Islam who are considered their enemies. Liberalism is a trick to justify the means, the clear agenda of which is to instil sentiments of hatred and universal hostility towards Islam. Thus various ways were created to convey intent and objectives.
