I just had an amusing few moments reading the Google search results for "Nick Griffin wanker". That Asian guy was only voicing a very widely held view. I would go further, and say that Nick Griffin is a c***. In UK terms, "wanker" has overtones of being not only stupid and ineffectual, but also publicly ridiculous, and "c***" the same, but with an additional dominant element of plain nastiness. "White bastards" sounds like something the BNP guys made up.
