Anyone who isn't dead in theory can be redeemed. This isn't saying people innately are good or bad (silly dichotomy), they are productions of conditions as others here have written and you can interact with them, manufacture conditions to a degree if you will. Yes, have to be extra wary with the openly reactionary types but that doesn't mean you can't engage and attempt to defuse them. Don't be foolish and assume they're friendly with 0 agitation and defusing ofc, even with a touch of this its dangerous, there are very few safe groups in the imperialist core you are fighting current condition benefit compounded with centuries of propaganda.

As conditions change what benefits lumpen and paid lapdogs etc will change, to plant the ideas of paths other than neoliberalism ultimately fascism is still critical work even if it can't be appreciated and taken into action now. Anyway, every revo group eventually comes to the point of needing to defend itself physically, so if you've totally alienated and cast off all of a group as simply 'bad', especially one with fighting experience, you've just fucked yourself over.
