I initially thought it may be linked to that Krekar twit, but seems to be exactly what you wrote.
My brother finally got a hold of a friend in Norway and he too thinks it’s a attack on the Labour Party by a single nut (perhaps part of a small group).
That’s quite distressing.
When I think of political violence, Norway doesn’t spring to mind right away.
I too thought about Mullah Krekar, but then again, like most mullahs, he’s just talking out of his @$$, so anything he’s saying I take with a big grain of salt.
Now if he’d specifically said, “I’m gonna sic one of my white homies on ya’all”, that’s a different story. But he didn’t. He just said Norway “would pay a heavy price”, so that way, if there’s some catastrophic lutefisk shortage, he can spout off, “I told you so!”
