True. Anders Breivik was partly inspired by anti-immigration screeds by American fundamentalists.
I am an optimist (albeit in a tangential way), but I choose to believe that the depths of the Great Recession, with all the Obama hatred and immigrant hatred and fundy zealotry here, and all the Neo-Nazi crap in Europe, was Peak Derp. The brownshirts are always there, under the surface, waiting for popular discontent so they can blame minorities or intellectuals or social liberals, but we may have weathered it this time. Nobody (and this utterly amazes me) has gotten off a shot at Obama. Breivik was horrendous, obviously, and shows what these guys are capable of, but it was a single incident, not a mass movement. There are Nazis in the Greek legislature and UKIP in Parliament, but they aren't the majority party.
And that was a bad world financial crisis, and it came right at the heart (not coincidentally) of an atrocious war motivated in basic ways by the dumbest religious fanaticism on both sides, and in other ways by economic elites fattening their bank accounts.
It could always unravel at any time, of course -- it always can -- but if you looked at the risk factors for a lunatic far right junta seizing power in one or more western democracies, the 2002-08 period scored high across the board. They even had legions of Father Coughlins dominating the air waves, and still it didn't happen. We could have had a repeat of the 1930s, but there were just too many educated and tolerant people who beat them back. Maybe Democracy has adapted a new part of its immune system. Maybe the US in particular is growing diverse enough that the old product "quick to judge, quick to anger, slow to understand" just won't sell here anymore.
