The problem is the BNP (under another manifestation, perhaps) will always be with us. The way to reduce their effect is not to attempt to ban them - a legal minefield which may well backfire - but to make them unneccesary. People turn to these groups when times get hard and they feel there is no one to represent them. Who have we got in 'official' politics: Pa Broon, who supports the bankers, abolished the 10p tax band etc etc, or Dave Snooty, who is quite unknown - and a Tory. To add to this, the recent expenses scandal has discredited politicians even further. So don't vote for the usual candidates but vote for someone who will look after the common man (and woman) and who knows the cause of all our problems: immigrants or some other minority group (not bankers, heavens no!) I understand Martin Bell (the Man in the White suit who isn't Alec Guiness) and Terry Waite are forming an 'honourable' political party to divert votes from the BNP; this would seem to be a way forward.
Intelligence tests have nothing do do with intelligence tests and only measure the ability to do intelligence tests. I remember questions like: 'tea is to leaves as coffee is to....'; in 40's Britain that measures social class. And 'Can a cat see in the dark; yes or no'. An 'intelligent' child would surely either say that's a silly questions or give the answer that would be considered wrong.
