I'm more surprised by the movement in this direction of people like Tommy Robinson, former leader of the English Defence League (discussed in the article intro). I thought of this kind of far-right as more of a "clash of civilizations" type of cultural and/or racialist right-wing, defending "the West" against foreigners and immigration. They did not historically have much of a religious angle to them, nor particularly care about social conservatism (other than opposing immigration). It feels like a genuine change that people in that camp now find common cause with Islamism against a shared enemy of Western liberals.
