Yes, what you do every time. Start a thread to stir up **, troll for bit then b****er off. Bravo, well done.
No politician has said it- but some people in the street, in doctor's surgeries, in front of mosques, in schools- have been saying it.
But most importantly, those immigrants that have shored up our hospitals and many industries and agriculture- won't stay if they feel unwelcome. And won't stay if they can't earn good money for their services. Many send money home to educate their children, or pay for parents' health care, many intend to go back one day, having saved enough to buy their own home back home and security. Why should they stay?
Some are committed to stay as they have adopted the lifestyle and enjoyed it- as I did all those years ago. But how long will they enjoy this if the atmosphere turns sour against them, and their kids are bullied and threaten at school?
