Here's why:
* Surnames are not always indicative of caste: In many parts of India, surnames can be adopted for various reasons, including profession, place of origin, or even ancestral titles.
* Caste is a complex system: The caste system in India is extremely diverse and nuanced, with various sub-castes and regional variations.
* Respecting privacy: It's inappropriate to make assumptions about someone's caste based on their surname, as this can be sensitive and personal information.
Instead of trying to determine someone's caste, it's important to focus on respecting individuals and treating everyone with dignity and equality.
