It's just the Mail doing what the Mail always does. Yes the demographic of Dewsbury and Bradford have changed massively since the 1950's. Ethnic groups will always tend to live in one area, especially when they first arrive in a country. The issue is the rise of extremism, where some people within the community become radicalised and end up doing what this latest young lad has done. Which is grim and needs to be addressed urgently somehow. But I imagine most people in Dewsbury are just getting on and living their lives. It's not scary, it's not terrifying, it's just a concentration of one ethnic group in one area. Which the Mail love to
round upon and reinforce every stereotype they possibly can.
The area I grew up in was a white lower middle white area before an influx of European Jews moved there from the 1900's to 1940's. If the Mail had been off on their UK rants then, they'd have focused on the little CofE primary school I went to, closing on Jewish holidays because it wasn't worth keeping it open for the handful of non-Jewish kids and suddenly needing to provide Jewish assemblies etc. How there were Jewish butchers selling their dubiously slaughtered meat, messy gardens, noisy kids, people wearing strange clothes and building synagogues everywhere and that the place was nothing like it used to be. However, we were all getting on with building up new lives, our neighbours were accepting and kind in the main but it would have been so easy to focus on the stuff the Mail loves to rant on about. The issue is surely extremism that they need to focus on, not that the ice cream lady wears a niqab.
