I understand that having laws and actually implementing them are two different things. but i can tell u for fact that people dont care if you ask any question regarding religion or god or do actual blasphemy. majority of indian religion is non-abrahamic hence things work in a different way. there is no concept of blasphamy so riots based on blasphemy are really exceptions.
If you put together all the people died in riots in india since independence they would still be less then the number of people died in religious attacks in last 2-3 years. and yes people do get prosecuted in a huge numbers for rioting.
But then again this will become india centric discussion, the topic at hand is different.
I still stand by my opinion that pakistan would have been like india because it is just natural.
