Crow Sister and Jeddy have 'got it'; it's a complex issue that can't be settled by assumptions and name-calling.
As I've said before, Keith isn't a BNP supporter or a racist or a fascist - he's just like many of us; bombarded with figures and aware of a widely-held perception that there has been more inward migration (a less emotive term than immigration perhaps) in the past decade than there was when we were younger.
If that perception is wrong, then it's not going to be shifted by accusing people of talking shit, talking rot, being fools or any number of insults. The people flinging the insults around are no doubt sincere in their beliefs, and have the facts to hand to back their arguments, but shouting at someone and belittling them is not going to help win the case. I hope, for our children's sake, that the people adopting that tack aren't teachers.
Any non-partisan outsider viewing this thread could be forgiven for seeing a couple of bombastic bullies shouting down and ridiculing someone.
But that would just be a perception, of course, and they don't count...
As an aside, instead of simply giving a link and saying, "there it is; go figure", it would help the debate hugely for those of us who are less informed if the poster could give a brief but accurate precis or summary of the link, explaining exactly why it is important.
