The Golden Dawn, as of now at least, is undoubtedly one of the biggest embarrassments of the nation, along with nincompoop teenage/young adult Anarchists.
Moronic, meaningless violence and hooliganism, Illogical racism, Nazi sympathising, directionlessness. Despite what nonsense they might preach, they have no actual program, and they ponder only to sections of the block-headed lower classes, especially those with fetishes for flashy rallies, slogans and street fights. In essence they're just reactionary, and like the NSDAP, what prosperity they have achieved is solely due to the damaged economy.
Unfortunately, the Dawn is the only actual representative of a nationalistic right-wing "ideology" in the state currently, and thus they are to blame for the thoroughly incorrect and ill-founded idea most Greeks have about such concepts as Nationalism.
Something to have in mind.
