You’re either unable or unwilling to see that in an extremely impoverished country with poor documentation in areas where most of the population lives (rural areas), people aren’t going to have documentation to prove that they’re citizens. Now the ruling party has said that there can be subjective measures of proof such as the testimonies of neighbors, etc. The same party has shown time and time again with previous actions (such as already having declared an Indian war hero a non-citizen) that they will use this subjective measure to selectively accept the “proofs” of Hindus while claiming that the same from Muslims is insufficient.
Moving on to your beloved CAA, it arbitrarily selects non-Muslim minorities, including Hindus, in Muslim countries to get expedited (in reality immediate, since the waiting period of five years conveniently starts from 2015) citizenship. This to give them the right to vote. Huh. Hindus in India have recently tended to generally vote for one particular party. It happens to be the ruling party. Who would’ve thunk it. It’s almost like this law cherry picked groups of people to enfranchise who would most likely vote for the ruling party.
Now what do these two policies have in common? Well a person of reasonable intelligence could see two main outcomes from this:
The ruling party’s primary vote bank increases in size with the large number of Hindus who get immediate citizenship.
The ruling party’s primary opposition demographic (Muslims) loses citizenship and thus enfranchisement while they wait in detention centers for the case to settle (which in India, as we all know, happens rapidly, ethically, and without any political interference what so ever)
Now one could say “well this is just a potential byproduct and not at all the intent of the policy. The BJP has drafted these laws to give refuge to persecuted minorities and to combat illegal immigration”
That statement would ignore various religious minorities that are persecuted in neighboring countries but not included in this law (they also just so happen to be groups that, in an election, would probably vote against the BJP. No coincidence there at all of course) while also ignoring the severe pitfalls of the NRCs ability to effectively combat illegal immigration since a large section of the Indian population will be unable to provide sufficient papers to prove citizenship despite having lived in India for generations.
