A major row between Harvard philosopher Cornel West and best-selling author Ta-Nehisi Coates has triggered new debate about the responsibilities of the black intellectual, and the role of social media in public discourse.

Watch Post Opinions columnist Christine Emba discuss the row and its wider meaning with Post national reporter Wesley Lowery and Global Opinions editor Karen Attiah in the discussion below:

A guide to watching: The feud began Sunday, when West published an article in the Guardian calling Coates “the neoliberal face of the black freedom struggle.” Harsh.

The piece said Coates “fetishizes white supremacy” while he ignores Wall Street greed, elite indifference to poverty and U.S. imperial crime, especially under Barack Obama.

Coates pushed back, posting links to past work. It blew up online. And at the end of it all, Coates chose to leave Twitter altogether.
