It seems that the three main characters are supposed to represent the three main viewpoints one could take on national socialism. Murdoch-chan is Holla Forums, with the hardline stance of all non-whites must die and we have to do it right the fuck now, and anyone who doesn't share our vision must go with them. She is pushing the JQ hard, trying to force it on people before they are ready, thinking it will be the end all for redpilling people.
Dr. Murdoch is the civic nationalist, thinking that the other races do have a right to exist, but in their own countries. He thinks that with enough time and evidence, people will come to understand nationalism and that the races don't mix well and segregate on their own. He doesn't want to force people into asking the JQ because it might cause resentment or outright rejection.
Murdoch is lost between the two, still unsure of what he's really doing but he knows that he must do something. He feels like he's becoming a fanatic, no better than those he would fight against in his quest to save his people and reclaim his homeland. He looks to others, greater people who have come before him but feels let down by them and their failures. And yet, he forges on. He might lean towards murdoch-chan in stance sometimes, Doctor Murdoch at others, but he still has his own ideas of what should happen and what we should strive for. He doesn't have the whole story, but he tries to make due with what he has and knows.
They all have essences of being right, and each are also wrong in some way. The first two try to inject their particular brand of NS on those around them, not listening and trying to understand the position of the other and trying to reason. They fight, causing fractures and devolve into calling each other kikes and shills, which does nothing to help anyone but the enemy. They must band together to weather the storm that beats on their walls, and they can settle their differences later once the danger has passed.
As for murdoch the lost, he tries to reason with those who are being misguided and led by the enemy under the guise of le helpful normal man who is definitely not a merchant, referencing honeypots and the traditional view of neo nazis as skinheads who cause meaningless violence and tattoo themselves, driving reasonable people back to the left. He even calls them out on this, saying that they could be great if they hadn't taken on the guise their enemy crafted for them over the years. I doubt that the storm riders are meant to be Holla Forums in form.
Murdoch might not be /ourguy/ but he's trying to help. He's doesn't seem to be the kind of guy to be in everyone's face about this kind of stuff. His works are meant to slowly give the red pill, make people taste the fruit of forbidden knowledge and leave them wanting more. They must go seek out their own answers instead of being spoon fed and told what to think. He seems to take a neutral stance on the whole thing that happened between Holla Forums and TRS, maybe because he doesn't want to earn the wrath of one or the other, or maybe he doesn't know the full story himself. I don't know, and I doubt anyone on this board does either. MM isn't shilling for jews or fags in this video though, as I've seen people ITT say. He doesn't like Milo, as seen in one of the last few videos. It just seems that he wants a more reasonable approach while we can still fight back.
