Doing so might present some interesting challenges because the tenets of one religion will prove to be blasphemous towards another religion.
For example, Islamists may claim that Hindus are in violation of the Quranic guideline that prohibits idol worship. Christians might say Muslims are in violation of the belief that Jesus is the one true path to salvation. Hindus don’t have a blasphemy concept, but I am sure they will be able to come up with something too. And who will speak for smaller religions like Buddhism, Jainism, and Sikhism?
The trouble with blasphemy is determining which standard of blasphemy is India going to enforce? It just does not compute.
Blasphemy laws are stupid. That’s all that needs to be said about them. The Constitution does impose restrictions on free expression which may be used to counter “blasphemy”, but even those are ambiguous and outdated clauses that serve no purpose.
