I think you are underestimating these grass roots groups. Some of them are supported by foreign inyerests who want to undermine trust in the government.
So we are told, but generally I don't buy it. Certainly not just for moustache-twirling "destabilization" purposes. If foreign interests bother with fringe Norwegian issues, it's because they get something directly from it. It may of course be that e.g. Israel gives support of various kinds to groups like SIAN or MIFF, or Russia to groups which are critical of Norwegian military support for Ukraine. But even that doesn't give us right to dismiss these groups as insincere - it's quite a way from that to actual front groups and astroturfing.
Either way, I think the focus should be on the "respectable" corruption, not on unhinged noisy attention seeking outsiders.
