Abolishing sub-castes may strengthen rather than dissolve castes.

Evidence

But assuming that the fusion of sub-castes is possible, what guarantee is there that the abolition of sub-castes will necessarily lead to the abolition of castes? On the contrary, it may happen that the process may stop with the abolition of sub-castes. In that case, the abolition of sub-castes will only help to strengthen the castes, and make them more powerful and therefore more mischievous. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 946

This remedy is therefore neither practicable nor effective, and may easily prove to be a wrong remedy. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 946
