From sexual preference to diversity and criticism of racial prejudice, we see ourselves as more open and progressive than previous eras. Yet at the same time we are quicker to judge than ever. From a pronoun to a joke, a single breach of the currently accepted norm - on Twitter or in person - is enough to be ostracised. Leading politicians declare with pride their refusal to be friends with whom they disagree.
