Then UKIP would seem to be the party of choice for anyone 'genuinely worried' about the level of immigration to the UK. The BNP is fascism, plain and simple. I'm not sure that with houses being repossessed, jobs being lost because British companies are outsourcing, hospitals killing off their patients and schools still failing, that immigration to the UK will be that high on most people's agenda come May 6.
The judicial system has made it very difficult to just chuck out unlovely people from expressing unsavoury views. We hold dear the right to expression in all forms - the arts, the Press, online, in protest, and through a variety of organisations. Thus, if Nick Griffin can say whatever he likes, then so can other radicals, like them or not. Countering one extremist view with another isn't helpful, but it is the right of persons residing in the country to say what they like. If you want to quash the right to demonstrate one viewpoint, you have to quash them all. And that leads to despotism, of which we've had quite enough through the rule of royalty, thank you.
