How can I change this mentality? What can I do? Why is this mentality even so acceptable in the first place?
You don’t because that would require changing the fact that he sees benefit and personal interest in maintaining anti-imperialism and “Radicalism” as unrelated “subjects”. Good luck on doing that, I genuinely think you’d have a more successful time counter-recruiting against them and risking being a bit more “unprofessional” by actually directing people to the “Real movement” so to speak. Feels like a shitty thing to do, but genuinely you would need to change this entire singular guy’s mindset instead of just actually recruiting from the base that already exists and finding far more like-minded people to put material pressure on his ideology and how it’s being implemented in practice versus just “coming off as a pushy organizer”.
I feel as though I am going crazy.
Some shitlib has your email somehow and is using it to send you snarky bits about “Free courses on the huludoomer, stupid tankie”. Typically, shitlibs are like this; not realizing that their “online political courses” are just reaffirming slop meant to coddle their settler sensibilities.
