In his new book Public Morality and The Culture Wars, academic Bryan Fanning analyses what he calls the “triple divide” between conservative, liberal and progressive viewpoints, how the moral views of those three groups differ and how they clash with growing intensity in what we call the culture wars.

On this week’s Inside Politics podcast, he talks to Hugh Linehan about public morality, the debate over the limits of freedom of speech and why liberal and progressive thinking has diverged.

Bryan Fanning is Professor of Migration and Social Policy at University College Dublin.
