Material context matters, but anything that would help maintaining “soviet” organisation after the revolution. Truck drivers, bikers, hardware-capable technicians, but also nurses and medics, farmers, depending on the society maybe even programmers, and also military-capable workers.
It all depends on what sort of proletarian power structure you’re building and what are the key skills required to maintain and grow it both during repression and after victory. If there’s lots of rails, train engineers. If urban areas are sparse, maybe radio operators.
Definitely not my most rightwing view, but my most rightwing conscious position is that comrades should join and build up whatever organisations they can, even if they are right-deviationists or contain reactionary elements, and fight over those inside the organisations. This includes parties with settler, LGBT-phobic, misogynous among other deviations.
I also have another view that may be seen as rightwing here (and is definitely controversial) that settler-colonialism is not the principal contradiction in current day USA, North America, or most of the rest of the Americas. It’s first between the international bourgeoisie (with home base in the US) and the international proletariat, then between peripheral nations and the imperial core finance, military and cultural sectors, and only after that it’s between oppressed minorities (be they native or “imported”) and the national state repression force. Some day I’ll take the time for this struggle session.
