There is no point in pretending that the BNP doesn't play on (however unpalateable) people's fears. However 800,000 people (of whom probably 795000 aren't BNP members) cannot either be ignorant or swastika waving lunatics.
The difficulty for the major political players (Lib Lab Con Green) is:
The BNP is the only party ready to admit that there is to what ever degree you want to admit a clash of cultures between the indigenous, judaeo christian moral relativist liberal black / white majority and the Islamicist minority who are fundamentalist in their belief. Most Muslims do not take part in the greater society we live in but choose to remove themselves and will move further into their own orbit when given Madrassas (titularly 'Schools' but little more than Hate Factories). The Moslems detest most of what passes as western culture and society - alcohol, gambling, capitalism,contraception, liberty, choice etc). Their Mullahs and Imams - mainstream NOT extremists - teach that homosexuals should be stoned, victims of rape should be punished, corporal and capital punishment are the right way etc.
Muslims finally say these things not for any rational reason but because God tells them to via the Koran.
People are really frightened; especially at the plan to give Islam a status of complete immunity from Law under a Religious Intolerance Act which will criminalise even reasoned arguement against the Koran.
At the same time we have the degrading spectacle of the candidates for the recent by election in Leicester grovelling in front of gangs of 'Community Leaders' pleading for votes from Islamicists who form a minority within Leicester.
No I dont think the BNP will turn from the electioneering route to power. The BBC documentary is gold to Griffin and his pals; whilst the borgeouis elite who can't tell the difference between race and religion continue to brown-nose Islam Nick and his pals will continue to thrive and the liberal elite only have themselves to blame
