No one I know supports the caste system and as a person with Indian parents living in California I cheer this bill happening. People from South Asia aren’t a monolith, and my understanding is that caste based discrimination is more common in the Bay Area than other parts of the state, but either way discrimination based on religion, sex, gender, race, ethnicity, income, or any sort of box you can end up in that you don’t choose to be in should be illegal under the civil rights act.
