Is Blasphemy Legal?
It depends on where in U.S. you live in. Blasphemy is the act of insulting or showing contempt or lack of reverence to a deity, or sacred things, or toward something considered sacred or inviolable. According to Pew research Center, about a quarter of the world's countries and territories (26%) had anti-blasphemy laws or policies as of 2018.
In U.S. blasphemy laws of some states are meant to protect the religious beliefs of a majority. By contrast, in some other countries, blasphemy laws serve to offer protection of the religious beliefs of minorities.
Blasphemy laws are supposed to provide redress to those insulted or harmed because the harm was to their religion. For instance, in these states it would be unlawful to vilify the religion and religious groups, defame the religion and its practitioners, denigrate the religion and its followers, offend religious feelings, or voice contempt or disgust of the religion. In some states, blasphemy laws include hate speech laws.
Article 20 of the International Covenant on Civil and Political Rights mandates that countries adopt legislative measures against "any advocacy of national racial or religious hatred that constitutes to discrimination, hostility or violence."
However, it is never easy, at least in the United States, to successfully prosecute or prevail in a case against a person or a group for violation of the blasphemy laws.
