Yes lets deny anything that dispels the argument that immigration is a new thing.
Have a look at the BBC link above Joe
(here it is again for you). It outlines the history of immigration (to the UK), from years 250 to 2002... that certainly includes 'living memory'. It ends by saying:
Fifty years after the start of mass immigration to the UK, questions are still being asked about whether or not the UK can become a multi-ethnic society at ease with itself - or whether there is still a long road to be travelled.
Of course, the questions, debate, conversations etc surrounding UK immigration have been going on a LOT longer than the last 50 years.
Let me point out, I'm not saying that immigration isn't causing the UK problems. I'd certainly stand with those that say it is, from jobs to housing. But the argument is constantly overrun with idiots who have the mentality of a caveman. Immigration has ALWAYS gone on in this country and will continue to go on. As I say, I agree that it is becoming a problem but lets discuss the problem not who one bloke is willing to pass a ball to or not!
