Walking through my small town this morning was a salutary experience. It seemed that 10-20% of those on the street were black or 'of Middle-Eastern appearance'. They stony-faced, looking straight ahead, locals exactly the same.
Item: two blacks come into the coffee shop. Conversation stops, then slowly resumes
Item: Black woman, trailed by a swarm of kids, leaves a supermarket with laden-down trolley. Local hardman points out loudly "and we're paying for all of that". Woman looks stonily ahead.
Genuinely - I'm not in any sense condoning this kind of behaviour.
The point is - this is what happens when large numbers of visibly and culturally different people enter a local population. And as we now know through an avalanche of empirical evidence, this will only get worse as time goes on.
What mugs we are.
