The right to grow a moustache has become the focus of rising caste tensions in western India. Several men from the Dalit caste, formerly known as ‘‘untouchables’’ and the lowest rung in India’s pernicious caste hierarchy, have been beaten up and stabbed for sporting a moustache in the western state of Gujarat over recent days. Highercaste men have apparently taken it upon themselves to enforce an ancient tradition that their ‘‘inferiors’’ should not grow facial hair. A moustachioed online protest movement has sprung up in response, starting with friends of the victims and expanding to other Dalit communities. Many have posted photos on social media of themselves raffishly twirling their new face furniture. A movement to end the ‘‘untouchable’’ stigma within 30 years was launched in Gujarat recently, with more than 1000 Dalit villages signing up.
