http://en.wikipedia.org/wiki/Strasserism"Strasserism refers to the strand of Nazism and neo-Nazism that called for a more radical, mass-action and worker-based form of National Socialism, particularly
hostile to finance capitalism from an antisemitic basis, to be initiated
alongside nationalism."
It's named after two Nazi brothers who were influential in the party and
urged that it take a more socialist strategy in opposition to others who wanted a more ordered authoritarian regime and not "the radical and disruptive program proposed by the Party's left wing".
"Strasserism, therefore, became a distinct strand of neo-Nazism that, "whilst holding on to previous Nazi ideals such as militant nationalism and anti-Semitism, added a strong critique of capitalism and framed this in the demand for a more "socialist-based" approach to economics.
"During the 1970s the ideas of Strasserism began to be referred to more strongly in European far-right groups as younger members with no concrete ties to Hitler and a stronger sense of anti-capitalism came to the fore."
The poster was arguing that
the Alliance of European National Movements formed by several right wing national parties in the EU parliament was really a left wing movement (albeit a racist and anti-Semitic one) because it supports economic nationalism (tariffs, strict immigration controls, no trade agreements, and British jobs for British workers) and opposes globalization with its effect on national (particularly economic) sovereignty.
I don't consider any movement that has racism and anti-Semitism as core principles can ever be considered a left wing movement, not matter what other policies one might agree with.
