From sexual preference to diversity and criticism of racial prejudice, we see ourselves as more open and progressive than previous eras. Yet, many proudly refuse to be friends with people they disagree with. 17% of Americans admit they have cut off a family member who voted for Trump. 20% of British relationship counsellors cite Brexit as the top cause of relationship breakdown.

Columnist and free schools advocate Toby Young and international news correspondent Myriam Francois debate the future of tolerance.
