Again my point and you still haven't answered. Going by your words, why do you think in India, people are not "supportive of rights of immigrants and other religious groups" ?
They probably are most culturally, religiously, linguistically etc diverse than any other country in the world. Yet minor issues aside they have decades of peaceful co existence.
I assume you are not from India, so why would you look at a country like that and have an opinion that they are heading to something bad. I'm genuinely curious.
Edit 1 - To add another point they have the most population in the world even. So, arguably, you are looking at the most complicated, functioning democracy in the world.
My point is, as an example, democracies with dominant religion as Christianity has its religious imprints within the governing body. A simple example to prove this is that all public holidays mostly are serving the dominant religion. (I didn't say Christianity is a common trait of successful democracies).
Wouldn't etho/religious supremacy apply here ? Why do you have the lens when you look at a country like India ?
Disagree. Most democracies, even though on paper are secular, always have imprints of the dominant religion. Democracies dominant with Christianity haven't "exploded", so why would this ?
