Morgoth gives Spencer entirely too much credit here. Spencer is not highly intelligent. He's not big-brained. There isn't a coherent intellectual core to what he says. His statements should not be analyzed intellectually. They simply need to be diagnosed.
Spencer is a midwit, a narcissist, and a fantasist. I first met him in 2009, and even then, his basic pattern was clear to me. He's primarily motivated by a desire to seek attention (positive first, of course, but when people naturally tire of him, negative attention is good enough, as long as you are paying attention to HIM).
Spencer's main routine for narcissistic attention-seeking is to set himself up in a particular ideological community (first conservatives, then the dissident Right) and then to signal hard against that community's natural assumptions. This is how he backed himself into advocating ethical child porn because of his hatred of conservatives.
You can't arrive at the truth by simply negating the views of other people, except purely by accident. But Spencer is really indifferent to truth. Everything he says is just a narcissistic game. Which is why he should simply be ignored.
Spencer is also at heart a fantasist which leads him time after time to be a fool. He looks at the EU and instead of seeing it as an enemy of Europe that must be destroyed, he imagines what HE would do if he ran the EU. I once likened it to an officer in a trench under artillery fire refusing to attack the gun raining death upon his men because he fantasizes about how HE would use it. Spencer clearly wants to be Macron. He fantasizes about what HE would do with an EU army, even though in reality, it would be used to crush nationalism. Spencer fantasizes about being the Schmittian sovereign, so he applauds state power, even when it is being used to wreck our societies or crush our movement. Of course, state power falls rather lightly on Richard (so far) because he comes from money.
Spencer has always been a fool and a traitor at heart, because real devotion to the true and the good is meaningless to a pathological narcissist. Calling openly for censorship of the movement should make his folly and treason clear to every serious person in this cause.
I hope Ed Dutton is hanging out with this mattoid simply to collect material for another fascinating HBD-based expose like his biography of Phil Rushton. If so, he's playing a dangerous game. At this point, continued association with Spencer looks more like bug-chasing than clout-chasing.
