Interesting comment from the black Labour MP Diane Abbot on Andrew Neill's This Week programme. Abbot's heritage is Jamaican and she knows all about integration having read history at Cambridge (tutored by Simon Schama) after grammar school and made it to Parliament. She pointed out that while most immigrants gather together initially (e.g. Italian areas and Irish areas in New York in the early C19th), gradually they are assimilated into the society of the country they have joined. In the UK however, parts of the Muslim community are going in the opposite direction. The children of these Muslim immigrants are more likely to use their religion to define themselves, wear hijabs, full face veils etc and take an exclusive, insular approach. Worrying.
On the contrary, i think identifying with your faith is a cornerstone of many immigrants identity. Again you make sweeping generalisations. Irish Catholic immigrants still go to mass, immigrant Jews still observe the Sabbath. Why shouldn't a muslim woman CHOOSE to wear the hijab ?
Twenty five years ago i recall many Irish people in London being demonised because of IRA bombing campaigns. It was wrong then to tar them all with the same brush, just as it is to believe every muslim is a Daesh follower
