Twitter CEO Jack Dorsey has been accused of hate speech in India after posing with a sign saying “Smash Brahminical patriarchy, criticising the country’s caste system.

The sign was given to Dorsey by a member of the Dalit, the lowest caste, and has angered Brahmins, the highest class, as well as Hindi nationalists who seek to downplay the religion's fissures and unite the country under a single cultural and political umbrella.

The company has since apologised, saying neither Twitter or Dorsey support the signs message to dismantle the Hindu caste system.
