This "Think Tank", "Freedom House" is NOT impartial; their methodology is flawed, biased and highly subjective. I wouldn't take any of their reports seriously, particularly when it comes to a country like India whose "Diversity" on various societal axes are truly one of a kind. The situation on the ground is much more nuanced and reports like these only create more harm.
Some criticisms;
