Peter, when I said the muslim thing I obviously wasn't talking in terms of political parties, I was speaking about the preaching of hatred; the BNP and the extreme Muslims are very similar in this sense. They both work behind closed doors to spread hatred, and that's something that everybody knows. And for the record, there have been many cases of several preachers spreading racism against the west who HAVEN'T been stopped and detained. No wonder the people of this country are angry, no wonder the BNP are angry! Try and look at it from their point of view; an outsider storms in and starts preaching about how bad the country is, how evil, etc etc, and there it really is a difficult situation because everyone's so obsessed with political correctness that it's hard to decide what action to take. Also, you're forgetting the wealth of history that this country has and the pride many people retain for this country due to it's history, which further promotes resentment towards the "invaders". Yes, you're thinking about this on a very basic level, I think, which you shouldn't do, not with something like this.
Either way, this isn't an issue that will majorly effect you in your lifetime so don't worry. If you want to worry about anything, worry about the Chinese - they're slowly turning into the biggest danger :ninja
