There is something rotten in Australia

[Furunculus]

A supporter of a fascist is also a fascist, or at best a complete idiot.

or someone who realises that mainstream politics doesn't represent them, but a protest votes to a fringe party that the mainstream consensus wishes to remain an isolated fringe may result in a reappraisal of the mainstream consensus, and thus result in a more representative democracy.

anyone who thinks that the vast majority of those BNP votes were dyed-in-the-wool fascists is an idiot.
