1. Nobody was stripped of citizenship. They couldn't prove they had it in the first place.
2. You won't learn this from the media's narrative about it, but: the reason why most protestors are protesting the Citizenship Amendment is not because muslim refugees (from Pak., Bangla. and Afghan.) are excluded, but because everyone else (non-muslim refugees [i.e. persecuted religious minorities from these officially "Islamic states"]) is now automatically granted Indian citizenship. Protestors are worried about loss of jobs and demographic replacement by these new citizens. So, most protestors are not protesting muslim exclusion, they're protesting anyone's inclusion.
