For Ayaan Hirsi Ali: 'It is a matter of principle that women are free  and equal'. This means zero tolerance of cultural practices such as  honour violence, forced marriage and female genital mutilation (FGM). In  her talk, Hirsi Ali challenges the audience with questions such as  whether multiculturalism is indifference disguised as tolerance, and  what do Western feminists have to offer to the life and death problems  of women from the developing world?
