Part of the answer is that the neo-Nazism in Greece was blatantly anti-Semitic, openly defiant of the EU, and it was a symbol of a criminal organization using the cover of parliamentary immunity to commit a number of crimes that began to impact the mainstream of society.Why is this particular party so anti-Semitic when other neo-Nazi and neo-Fascist parties are mostly anti-Islam? Golden Dawn is anti-Islam, but reflecting the reality of anti-Semitism among a segment of the Greek people, it remains anti-Semitic more so than any other European far right party. After all, conspiracy theories involving Jews and the banks, Jews and the US government, Jews and the mass media remain popular, at least among a segment of the population that is looking for specific people to blame, instead of looking to institutional structures, for the problems in the world economy.
There is indeed a gap between the rhetoric of "political correctness" that politicians and media employ, on the one hand, and the reality of discrimination, on the other. In fact, even the neo-Nazi and neo-Fascist organizations are often careful what rhetoric to employ in public and what they use within their ranks. For example, xenophobic and racist rhetoric is always used in the context of what is popular among a segment of the population that sees a threat to its way of life from foreigners, especially non-whites. Given that the "war on terror" is institutionalized, it provides the ideal cover for far right groups to be claiming that they are simply on the side of those fighting Islamist terrorism when in fact they are pursuing a racist neo-Nazi/neo-Fascist agenda. Therefore, populist rhetoric becomes a way of articulating a message of bigotry that tends to find an audience with those seeking to scapegoat a specific group of people of the institutional ills of society.
Are asylum seekers from Africa and Asia the cause of neo-Nazism?
Italy and Greece have repeatedly complained to the EU that more needs to be done about the massive influx of asylum seekers. After the recent tragedy of the ship that sunk and took the lives of several hundred Africans, the Italian government once again appealed to the EU for help and asked that Greece and Italy were entry points for Africans and Asians headed for the West. The EU does provide some funding, but when we have war-torn and civil-war torn countries in a number of African and Middle Eastern areas, there are limits to what the EU can do because people will find ways illegally to enter European soil. Greece has set up what amount to concentration camps for illegals that are captured, while Germany as the richest EU country does provide preferential treatment for white immigrants vs. those of color. The same is the case throughout Europe. France targets non-whites and gypsies that many see as sources of crime. Finally, Norway, a country with the highest living standard, or at least in the top five in the world, has active neo-Nazis targeting Muslims. Unlike Greece and Italy, Norway is not under austerity, but a segment of its citizens wants socio-cultural catharsis. Here is where scholarship needs to take into account not a single cause for the rise of neo-Nazism in the West, but everything from historical, ideological, and cultural to economic and political.
