Research Aim: When someone speaks or writes profanely about a sacred or religious personality, place, or object, it amounts to blasphemy. The seculars and proponents of freedom of speech and expression do not hesitate to malign, mock and insult religion and the holy personages. However, blasphemy can enrage thousands and millions of believers worldwide as they cannot tolerate any disrespect towards their religion or holy personages, and they can become violent. In this study, the global blasphemy laws and how much they prevent blasphemy are explored, and their role in developing global peace is explored based on a survey-based study.
