It would be nice to think that by ignoring the BNP they'll just go away. Unfortunately the only thing that seems to work (as the late 70s shows) is to challenge them at every step. Otherwise the folk memory of what a bunch of thugs they are tends to fade wawy, and before we know it, someone like Nick griffin comes along and tries to turn them into a credible force. Unfortunately, as my local council shows, some people do actually fall for it.
