One of the major yearly exams got leaked in India last month so the BJP has been trying to suppress that news for some weeks now.
So they've launched a racism campaign against China where Indian bot accounts have "discovered" a secretive caste system in China which apparently is worse than the Indian caste system.
They're using two things to support their claims:
- Four Occupations System which has not existed for centuries
- Hukou system which is the Soviet Internal Passport system
This is just 100% cope to feel good about living in a failing state that is India.
It's always projection. For western libs it's "look at how poorly they treat Muslims in Xinjiang", for India it's "they totally have a caste system hidden in their society"...
