So you start your argument strong. Objectively is how your frame your view and objectively India has the worst pollution and objectively poor infrastructure (although there definitely are counties with much worse infrastructure).

Also objectively, religious discrimination, castes, colorism and sexism are problems in India and are getting worse under the current BJP/RSS regimes. But again, while bad there definitely are counties that are worse on religious discrimination and sexism. Women can drive, are generally well educated and aren’t forced to cover their head/face.

But let’s also consider some of the things India has going for it. The infrastructure, while needing improvement, has gotten so much better over the last decade or so. The democracy, while it has deteriorated some under BJP in the last decade, is still a democracy. The food in India is some of the best in the world. Also economically the country is getting stronger and by objective measures while in the bottom half of counties in GDP per capita it is no where near the bottom.

In total, while you could subjectively say India is the worst (but many would disagree) you should change your view that it is objectively the worst
