There is no correlation between political polarity and intelligence level. All forms of extremism are dangerous, and to me, equally undesirable. Unfortunately the 'centre' point of British politics has moved quite distinctly to the right over the last thirty years. That is the real problem, of which the illusory 'rise' of the BNP is a particularly ugly symptom. I'm old enough to remember when the 'extremist element' (to put it politely) seemed mostly to be left-wing supporters inadvertently giving socialism a bad name. These people don't really care what they are supporting, it's just attention-seeking 'gang' stuff. They are being manipulated, but isn't that what the game of politics is all about?
