It seems to me that most bnp voters are people who are convinced (whether by media or general conversation) that there are genuine problems with the country, when this just seems to be fallacy.
First thing, the mp's expenses. I actually don't really see why this is such a big issue, i mean, compared to the entire government budget for everything (billions) it's such a miniscule amount that is being taken compared to it. The reason for the hysteria is that many people are looking at their claims and thinking "that's much more than I earn", with the majority of these people being working class (the bnp's target voters) because the mp's get so much compared to them on a whim. It does seem a bit unfair, but the mp's aren't destoying the system or seriously damaging anything, and besides, the mp's in england earn relatively little for such an important job (deciding the laws, pretty important).
What's happening now is that the mps can't argue against this because then they will instantly discredited, and some good politicians are being forced to leave because of doing what many were doing. I do agree some of them were a bit OTP with their claims (moats?), but in these scenarios the mps should be told to cut down on their claims and not claim for second houses which they make money out of by renting, and instead should be allowed to continue instead of pointlessly throwing them out.
The most amazing thing about the mp expenses scandal is the idea that politicians are very different to normal people; yes they all have similar skills needed for the same career, but they're still essentially very similar to everyone else. If the bnp (or generally the public for that matter) had the same number of mps in parliament as there was in the scenario before the scandal came out, i doubt that a different proportion of people would have claimed for expenses illegally. There seems to be absolutely no empathy for the politicians, who after all are people who have gone into politics because they wanted to.
Secondly, this lack of empathy that the bnp holds for people who appear to be different from the average white working class person is what the party is based on, hence the hatred for black people and poles etc. The lack of understanding of the fact that all people are very similar shows why they think their policies are right. Everyone who doesn't vote bnp knows that if all immigrants left the country then the economy would be crippled much more so than it is now, and crime rates would not change because there is always an underclass in any society that commits crime, no matter what race. The bnp just simply don't understand that if the situation was reversed then they would be exactly the same as immigrants.
Finally, the economic meltdown is not the fault of the government. Granted, some measures could have been put in place, but this would have just been miniscule damage control; the bnp don't understand that it is a GLOBAL economic meltdown, and regardless of which party was in power there is no way that we would have been much less affected. The bnp try to patch the causes of the problems to their beliefs, but don't really provide evidence that their beliefs hold true.
The bnp just seems to be a bunch of people who, frankly, just don't understand what is happening properly, and have convinced themselves that their beliefs can have some relevance to the problems in society.
