Because decent people do nt question immigration with a distinct "why are they here, why do we pay" and other rot, which denotes the speaker as a racist.
And where you really think you have a point, why is it that you never actually question all of the UK immigrants leaving to Canada, the US, New Zealand or Australia.
The person who asked the question, too damned scared of open debate, the sign of a good home grown racist, mails me direct with a suggestion that I read the papers. Hmmm, firstly, not the rags you read.
As to 'open house', stop reading crap newspapers who fil your head with this drivel, and understand that it is not as easy as they say.
It's all just racists, and you, another little dummy, go along with it. As to small minded,meaning literally that, small minded, closed to other possibilities, even handed, tolerence, understanding and much more.
Now go look at your question again and understand who is 'small minded'.
