Comment on General Election 2010 Poll Results by Kelly.

Firstly, no one would be ‘removed’ under the BNP, unless they are illegal or foreign criminals. The party continually says the problem lies with the politicians, and not entirely with the people who come here. The Party has a problem with the Islamic faith, and not necessarily with individual Muslims.
As unemployment is expected to hit 4 million, there should be no shortage is potential workers. If you read the BNP policies on Housing & Welfare you would learn that the current benefit system would be scrapped and those able to work but refuse to do so, would lose all financial support from government.
People of foreign decent would be offered grants, but I doubt you would see mass movement of people returning to their country of origin. The aim of the policy is lower the population and ease the strain on social services and communities. The hope is that the BNP would make the country less easily taken advantage of, and that would consequently put off a lot of the low life scroungers who have come here over the years with the sole intention of milking the system and taking advantage of our over hospitable tolerance. There would be no more foreign religious buildings, translations, festivals etc.
I believe most people who would take up the offer would not be well-settled skilled workers with a decent paying job in Britain, like a dentist; so I don’t think you should worry. Although I’m sure a loss of people from the country would ease the strain on the NHS and the demand for dentists, nurses and doctors would not need to be so high.
