(I'll work out a neater and more concise list, just throwing some stuff out there for the time being)
Sure, but with the disclaimer that position-taking is itself at odds with the larger framework in question. That said, manifestos are about taking positions. So for an alt-left, I'd be asserting positions not purely because I'd condone them through and through, but perhaps because it would be a step forward, net if not gross, if people adopted them.
So what would an alt-left consist of?
It would largely be based on a skepticism of how socially progressive rhetoric can be used to distract and disarm. That said, this skepticism is usually voiced by people, seemingly, who aren't substantially concerned with social progress, or perhaps even oppose it.
All the talk of schizo could figure in in an integral way, but I'm not sure how. Could be that the alt-left would entail more of a conscious and constant reorientation of itself, feeling out the political landscape from a variety of ideological perspectives, trying to tap into this and that ethos, administering their developments, etc. This is where it could start looking like something esoteric and mystical, so perhaps not practical.
But it would largely be situated in that horseshoe territory. CCRU would be considered a sort of forerunner, or grandfather group of the alt-left.
Ideally it would be a cosmic progressivism, but again I'm not sure how that would appeal to most people. That is, it would base human agency and revolutionary potential in much more primal and integral physical processes - but now we're entering territory too scientific or technical for most interests.
It should be hard work, but I think concessions need to be made there, if we are to entertain the possibility of actually gaining traction/support.
Those involved in DiEM25, Progressive International, etc. could be close to the territory I'm describing.
But what could be innovative about an alt-left would be that it could develop a symbiotic relationship to capitalism, rather than constantly pouting about it, at a loss. Wouldn't be accelerationism through, which, while a step toward the alt-left I have in mind, doesn't seem to prescribe clear enough and sensible enough solutions.
That is, the alt-left wouldn't be trying to hasten capitalism unto its unfolding, but it would be a midwife, gradually optimizing things and coaxing out potentially new political and economic eras.
It would be a project toward communism. Just with new and experimental guidelines and strategies.
