No, it's not. It's all a lie. The blunt truth is across the 1991, 2001, 2011 and 2021 Census *every* ethnic group in the UK has become *less* geographically segregated and *all* groups, majority and minorities, are more likely to interact with people not like them.
Outstanding piece by Stephen Daisley.
Ethnicity is no barrier to Britishness - it's culture and integration.
That means 'smaller cohorts and aggressive integration policies' - and tackling the institutions that 'have amplified grievance narratives and radical anti-Western ideologies'.
