thats right... life is more complex than black and white, left and right, absolutist positions - on the left there is a tendency to be absolutist, I would say, and it does us no favours.
I'll run you through it again:
Imagine you are in a small minority of British Anarchists in China!
You arrive feeling alienated, expecting the state and broader culture to be against your ethnicity and beliefs.
Then the state sets up a British Anarchist school to send your children to, and goes out of its way (through positive discrimination projects) to make you feel included.
You respond to this courtesy by engaging better with the state, and ultimately relax about being in another country.
There is a carefull balance that must be struck between creating net inclusion out of seemingly exclusionary state policies, but there is much research to prove that this does have a significant psychological effect on minorities and helps them to feel valued by the host state.
The absolutist position is the French route - all citizens must be loyal to the republic first and foremost - all religious clothing banned from schoold etc.,
I would say that the UK has better race relations than France, and possibly than any other country in the world - in no small part to a policy that allows people to "do their own thing" rather than forcing them into a narrow mould of "Britishness", whatever that might be.
Its more complex this way, its subtler, but i think it is the right way to go.
