The people in my village are probably arriving home this evening to find their doorsteps littered with something even more unpleasant than a cat turd. Yes, the BNP have been out delivering hate filled leaflets full of contradictory myths that they claim to be fact.
I cannot be bothered list all the errors and lies they claim as "facts" in their leaflets, but needless to say if you are blaming the EU and immigration from Europe for the vast majority of immigration in to the UK, you can hardly claim that the UK will have white people as a minority in 50 years time, after all, most people from Europe are also white people.
As I said, it doesn't take a large brain to work out that if the BNP cannot get this simple fact right then there is a good chance that their other "facts" are equally wrong and misleading.
Still, there are plenty of thick people about who believe such rubbish or articles in the Daily Mail claiming we will be overrun in 50 years time.
A good argument stands on its own merits, but if you'll have to lie, you've lost the argument.
