You've got it wrong entirely. Just because you dissolve discrimination, it doesn't magically kill segregation. Castes were created way back when they were used to classify people based on the work they do, and young ones continued in the steps of their older generations in their job so it was a mere classification of their family's work. Then it started going ugly when people in respectable jobs wanted to protect themselves from "outsiders" taking their jobs away.
But it just doesn't make sense anymore. No one is following their elders' job anymore. The caste system itself must be outlawed even to mention it.
As long as you still try to identify someone based on their caste, you are encouraging segregation. Govt forms must not include an outdated classification.
I shouldn't show proof of my caste to get a college admission. Marriages must not made based on it.
I kid you not, I was personally rejected from marriage with the woman I was in a relationship based on my caste.banning Discrimination did snt do shit.
