True if you know all the caste names, but a lot of caste names in the south don't fit into the four buckets used in the north. Which makes for a very interesting discussion.

Due to the actions of EV Ramaswamy Naicker, a lot of Brahmins from Tamil Nadu were forced to give up their traditional surnames, and made to instead take on their father's names.

Ah, found the racist brahmin. First time I'm hearing this passive aggressive "Naicker" attached to Periyar's name.

I'm torn between calling you out and asking for a source for your claim. Going to do both.

Salty much? Plz link to source lol.
