In every census since India was born the governments tracked religion, except the last one in 2011. That's for a good reason; the Muslim population percentage is said to be surging forward and the govt. in power didn't want the majority community to start worrying about its existence (it has good reason to do so, as Hindus have basically been wiped out from every Muslim majority region of South Asia)
By various accounts and projections, the Muslim population percentage in India now is around 17-18%.
There is this question of what definition one uses to define a Muslim to be a violent radical. By all accounts (including various polls) such percentages are low even in jihadist infested countries such as Pakistan.
But I think what's more relevant is the ability of violent Islamist groups to form and sustain themselves in a community. I have developed a new way of looking at this (this will be published in a 12,000 word academic journal article, due out in July -- for your information, let me tell you that I refer to a lot of data from the Pakistani Muslim immigrant community in the UK).
As someone with considerable exposure to the ongoing violent radicalization of Indian Muslims (as in my 2009 book), I can tell you that, Indian Muslims are now undergoing second generation process of radicalization. The Indian version of Tahreek-e-Taliban (modeled after the famous militant group in Pakistan) has just been formed in the central Indian city of Aurangabad. Few years ago the security agencies unearthed a massive arms haul there, that included extensive light arms, enough to equip a small militant group.
In 2008, India's National Security Advisor admitted that there are at least 800 terror cells operating, presumably in India's Muslim communities, supported by the likes of Pakistan and assisted by the Saudi funding. Indeed, India is primed to have its own version of Boko-Haram very soon. The underlying process are specific to Muslim communities and are assiduously cultivated by external Islamic governments (of course, the Western governments are busy blaming the local government(s) for what are mostly self-induced Muslim community-specific processes).
What this says is that the Western governments should get their act together and help India led by Mr. Modi, and not undermine him, as I believe they are primed to do (by trying to constantly put him on the defensive). That would be a strategic blunder.
Unless the current trends in Islamization are quickly and permanently reversed, we are looking at an India that's also going in the direction of Nigeria and more.
