Single identity road to disaster

Interesting op ed by Amartya Sen in the FT which attacks the single identity approach to culture and politics. He argues:

A single-focus approach is a good way of misunderstanding nearly everyone in the world. In our normal lives, we see ourselves as members of a variety of groups. The same person can be a British citizen, of West Indian origin, of African ancestry, a Muslim, a vegetarian, a socialist, a woman, a jazz lover, a teacher and a mathematician. Each of these categories gives her a particular identity. It is for her to decide what relative importance to attach to these affiliations, in any particular context. Central to human life are the responsibilities of reasoned choice.
