If you’re a pound shop politician desperately angling for populist clout by claiming you’ve seen no white faces in some place you visited then I have some advice: If that’s truly what you’ve observed then it’s not evidence that BME migrants don’t “integrate”. It’s evidence that the whites won’t integrate. It’s evidence all the whites moved away when visibly “foreign” newcomers tried to move in alongside them. By trying for racist clout you’ve shown prima facie evidence of whites being racist.
