With NCR everyone will have to prove citizenship(probably, govt hasn't given any clarification regarding this) regardless of the religion. CAB bill doesn't immediately give citizenship to non Muslims in India. It specifically states that its for people from those three countries. The people who is living in India who is not from these countries regardless of religion will be declared illegal immigrant(again, not clarified)
This is not a recent thing. Read about Assam Accord of 1985 https://en.wikipedia.org/wiki/Assam_Accord
The protests in eastern part of India is to uphold this accord. The current government has diluted the accord to give citizenship to these illegal immigrants(excluding Muslims, LTTE, etc) with the CAB bill.
Protests in eastern part of India is against giving citizenship to any illegal immigrants(regardless of religion) in India. In other parts its because, excluding a religion from giving citizenship to Illegal immigrants shouldn't be the nature of India although I think that its constitutionally valid(IANAL) (as they are illegal immigrants and constitution doesn't protect them)
This is not a case of `stripped of citizenship`. India just built detention camps for illegal immigrants in the country. I think every country in the world does this to illegal immigrants (and later deported). The protests that are happening in the eastern part of India is against giving citizenship to illegal immigrants.
