Ending caste belief naturally produces inter-dining and intermarriage.

Evidence

To agitate for and to organise inter-caste dinners and inter-caste marriages is like forced feeding brought about by artificial means. Make every man and woman free from the thraldom of the shastras, cleanse their minds of the pernicious notions founded on the shastras, and he or she will inter-dine and intermarry, without your telling him or her to do so. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 953
