The context of left - right is important as you say, and interesting. Is being left or right a total package, or is it originally a party's economic stance?
It is a very grey area.
But here is some Griffin, especially interesting is the "salable words":
"Without the White race nothing matters [other right-wing parties] believe that the answer to the race question is integration and a futile attempt to create "Black Britons", while we affirm that NON-WHITES HAVE NO PLACE HERE AT ALL AND WILL NOT REST UNTIL EVERY LAST ONE HAS LEFT OUR LAND." - Nick Griffin
"There's a difference between selling out your ideas and selling your ideas. And the British National Party isn't about selling out it's ideas, which are your ideas, but we are determined now to sell them. And that means basically to use these salable words.
As I say, 'freedom', 'security', 'identity', 'democracy', nobody can criticise them, nobody can come at you and attack you on those ideas: they are salable. Perhaps one day, once by being rather more subtle, we got ourselves into a position where we control the British broadcasting media, then perhaps one day the British people might change their minds and say, 'Yes, every last one must go'. Perhaps they will one day, but if you offer that as your soul mate to start with, you're going to get absolutely nowhere. So, INSTEAD OF TALKING ABOUT RACIAL PURITY WE TALK ABOUT IDENTITY." - Nick Griffin addressing the Ku Klux Klan
"Voluntary repatriation. Isn't that EASIER TO SELL than compulsory repatriation for all?" - Nick Griffin
