What @Tallboy is saying is very important for a few reasons:
1) The role of religion or lack of thereof in general in countries
2) Rarely, at least in this forum, we see Indians being so introspective and self-critical.
It is good to self-flagellate, once in a while. As my favorite philosopher Nietzsche says, 'even in a wound there is power to heal'. Pakistanis are experts in self-flagellation.
Anyway, what @Tallboy says above has been echoed by the right-wing Indian parties. I think I have seen similar attitudes by RSS/Bajrang Dal like voices. Now, one may be willing to dismiss such voices as 'loonies' because they sound so political incorrect. Just like the idea of Caliphate in Pakistan. But, beyond fora like these where we all interact and learn from each other, there are millions who think of 'pure India' being a Hindu India and the rule of Sharia in Pakistan.
Also, more than a few times, I have seen folks at Bharat Rakshak thinking along the same line: 'Dharmic' nations like India and Sri Lanka being essentially different from the 'Abrahamic' nations. I can conclude that they would like a vocal, expressive 'Dharmic' face of India. And folks at BR are a highly educated lot. We can't dismiss them.
I am not sure if India is ever going to be a superpower. It has many necessary ingredients but, perhaps, not enough. To be a 'superpower' or even a 'regional' power one needs the ruthlessness of Americans, Chinese, Israelis, Russians, and (pre-WW 2) Japan. India does not have it in its stomach. Neither does Pakistan, btw.
I will try to expound the last para later. But let's not shoot down the OP. It is an important debate.
