You're right. Russell Brand is a hardcore socialist and general knobhead. However, he's a loose cannon. The UK government is ran by the Conservative Party. In reality they conserve nothing and are actually fairly socialist, but hardcore socialists regard them as far right. Russell Brand therefore hates the UK government.

It's therefore not a surprise that someone like Russell Brand would speak out against WuFlu propaganda, given that he hates the UK government and the UK government have been big promoters of WuFlu propaganda.
