It isn't real. That's the point. It's made up arbitrary classification. Continuing to use it by calling people "lower-caste" is how it persists.

You're not describing reality since there is no such thing as a "lower-caste person". Stop thinking, talking, and acting as if there is.

You can't legislate your way out of it, you just stop doing it, including the language.

It actually has a genetic basis. According to David Reich in his outstanding book Who we are and how we got here, the varna/jati castes and sub-castes have been able to maintain a level of endogamy stricter than Ashkenazi Jews for millennia and there is 2-3x more genetic distance between two different jati groups coexisting in the same village than between North and South Europeans.

So basically you had a group of invaders who came to India, proclaimed themselves both racially and morally superior, and enforced a rigid system of miscegeneation laws to prevent themselves from being diluted. Makes the wildest dreams of white supremacists tame in comparison.

Of course, none of that justifies the discrimination. I don't know how to fix it either, India tried but hasn't succeeded. B. R. Ambedkar, the author of India's Constitution came to the conclusion that Hinduism is unreformable and that former untouchables like himself should convert to Buddhism, but that hasn't happened on a large scale. Subhas Chandra Bose proposed to abolish the caste system through socialism and inter-caste marriages, but he was an authoritarian bordering on Fascist.

Genetic differences don’t mean it’s not made up. It’s not like we studied people’s genes and went “hm yes you can divide this ethnic group into four subgroups, Science!” People made a system where they divided themselves, and over time that division resulted in some small but noticeable amount of genetic divergence.

But there are, like, trillions of different genetic differences between all of us, and you could draw totally different lines around people and find a genetic basis if you really wanted. The genetic basis is used to justify the arbitrary groups; the groups are not an emergent phenomenon of the genetics.

You're confusing cause and effect. The genetics did not emerge from the castes, the castes were an effort to entrench through religion the superior social status of invaders who were a different group with distinct genetics. They were not imposed from within by a faction of a unified group that subsequently diverged.

Race is made up, yet racial discrimination happens all the time. Money is made up, yet we all use it every day. Just because something is “made up” doesn’t mean it isn’t real. We made it real.

You're missing the point.

Instead of a law to stop "lower" and "upper" caste from discriminating against each other (like that comment was saying), the entire concept of caste needs to be purged.

That won't happen if you continue to use those very terms and then say it's (describing) reality. The sooner people stop dealing with it, the sooner it stops being a (real) thing.

I’m not missing the point, I disagree with it.

Like, who is “we”? In any situation where one group has structural advantages over another, there are going to be people who are very much not on board with merging the groups. If your plan to equalize everyone is just “pretend the groups don’t exist”, it will fail, because you’re simply ignoring a status quo that others are actively working to preserve.

Exactly true. Race, money, and caste all vanish from existence if nobody continues to use the concepts.

There are people who want caste discrimination to exist. Given that reality, should the people who don't want caste discrimination to exist simply pretend caste doesn't exist (and therefore caste discrimination doesn't exist) or acknowledge that the former group exists and try to do something about it?

So Castes exist but should people start using the phrase different-caste instead of higher-caste, lower-caste, etc.
