I don't see how these principles are particularly outrageous or ridiculous. You can tell quite easily what they're about from reading it: anti mass immigration, anti abortion, pro nationalism, law and order, sovereignty. None of these strike me as completely bonkers policies which won't wash. And during elections they're not going to be going round using such high-faulting language and talking about irredentist claims on the north.
I'm sure Barrett and Reynolds have been involved in politics long enough to understand that the hoi polloi won't be wooed by fancy language and abstract ideology. So I imagine their strategy for appealing to the masses will be different to their setting out their stall for prospective members (9 principles).
