The last ten days have seen major stories of racism in both of Britain's major parties.
What is happening in the Labour party - and Boris Johnson's comments this week - are frightening to many Jewish and Muslim people living in Britain.
This is a reflection of the way the politics of identity dominates politics today and attracts comments, sometimes critical or offensive, about particular groups.
I expressed this concern 2 decades ago in two pamphlets for the think tank, Demos. I would stress now, as then, that liberals view people as individuals, rather than through the prism of their race, religion or sexuality.
