Sorry, T. t. C., when you start denying a platform to someone you disagree with, then the cure becomes worse than the disease.

Loathsome though the BNP may be, we have to use open democratic ways to defeat them; otherwise they go underground and become even more difficult to counter.

They are riding on the wake of the mess that the main parties have created. It's up to everyone of all political persuasions to help put right the sleaze and corruption and then make mainstream politics more attractive. That way voters won't feel the need to register a protest vote with bigots like the BNP.
