Martin Sellner looks like an H&M model. But beneath the smile the 27-year-old philosophy student wears the sinister new face of Europe's extreme right.

Sellner is the co-founder of the Austrias Identitren Bewegung (Identitarian Movement), a collection of young, anti-immigrant Austrians who describe themselves as right-wing hipsters. The IB, as Sellner calls the organization for short, is rising in popularity in Austria. It considers itself among the most successful right-wing youth movements in Europe, and that is causing concern.

The degree to which the Identitarians have captured Austrias right-wing zeitgeist may be indicated by its rapid membership growth in the past year and increased media attention that the group's theatrical antics have garnered ahead of Sundays presidential elections in Austria.

Add the increasingly likely win for Norbert Hofer , presidential candidate of the right-wing populist Austrian Freedom Party, thanks in part to support from Sellner and his followers, and the Identitarians may see their extremist ideology, under the cover of refined young faces, mainstream even sooner still.
