Here's why:
* Surnames are not always indicative of caste: Surnames can be adopted for various reasons, including location, profession, or even a family's history.
* Caste is a complex social system: The caste system in India is a multifaceted and historically rooted social hierarchy. It's not something that can be easily categorized based on a single piece of information like a surname.
* Focusing on caste can be harmful: Making assumptions about individuals based on caste can lead to prejudice and discrimination.
It's important to remember that people should be treated with respect and dignity, regardless of their caste or any other social category.
