"In India, a surname is not a name. It is a verdict." Before you speak, your surname has already spoken for you. It decides which bench you sit on, which résumé gets a call back, which flat is suddenly "already rented", and which love may become a marriage. Three-quarters of a century after the Constitution abolished untouchability, caste has not disappeared. It has learned to whisper. The Surname Trap follows that whisper from the colonial census to the AI algorithm, and shows how ordinary citizens can challenge it with the Constitution, the RTI Act and the courage to ask questions. Inside you will find: • How a surname became a caste certificate • What the data shows: jobs, housing, courts and campuses • Your legal toolkit, with a step-by-step RTI guide • The voices that refused the verdict: Phule, Ambedkar, Periyar • Shri Mataji's vision of a religion without caste • Clear, sourced and written for every reader, not only scholars. For anyone who has ever been asked, "What is your full name?" and understood what the question really meant.
