Assimilation - Mission Impossible

Trevor Philips, a former head of the British Equality and Human Rights Commission and himself a person of color, recently had the following to say about the failure to assimilate of British Muslims. My source is Metro.UK:

The integration of Muslims will probably be the hardest task the country has ever faced. I thought Europe’s Muslims would gradually blend into the landscape. I should have known better.

The difficulty isn't news to anybody who has been paying attention.
