But the liberal pandering to these communities pre-dates all that. Ray Honeyford was sacked in the early 80s for daring to suggest that certain practices of the local Pakistani muslims in Bradford mitigated against good educational practice. Why? Because even then the fear of being called racist to people of brown skin trumped all other concerns for the sort of people who populate local government and the educational establishment. With time, it's got even worse.

The white liberal is still labouring under the delusion that this is still about race. It's not,They don't even grasp that the game has moved on from race and into ideology and practical considerations of the rule of law.
