Ahhh, so that's the source of it all. Why so keen to blame these people? Could it be something to do with Breivik's manifesto citing Spencer over 50 times (according to that bastion of Marxism and Islamism, the Daily Mail)?
I must confess I haven't sent Spencer an apology yet. It's somewhere on my to-do list in between "when Hell freezes over" and "when a member of the Kardashian family develops some dignity".
