Sorry mate, but your far right is not the same as our BNP. Really, it isn't. The BNP has no policies or ideas beyond get rid of anyone who isn't white, speaks english and is heterosexual.
Edit :As in the far-right you claim have power. I think a lot of reasons why the far-left, or even moderate left, gets no traction in the US is precisely because of the massive generalisations it tends to make about the 'enemy'. I could be wrong though, maybe some kind of strategic essentialism could work wonders there.
