I suggest Rosa Luxemburg’s Reform or Revolution to break people out first, less scary than Lenin, and a I think a “woman’s touch” does a thing for peoples minds under patriarchal norms, with the assumption that they’re somehow less capable of all of the things they’re afraid of. It was critical in my political education when I was starting off grabbing from everywhere to see what gripped the road I saw us flying down (Conquest of Bread sucked, never read more ‘kum-ba-ya’ utopian idealist tripe in my life, and I could tell that having barely even read much Marx at that point); and Reform or Revolution is more focused on dismantling the single topic. From there, once the reader are forced to mull on that reform will never save us, haunted by their discomfort and spurred by the sprouting seeds of their discontent the only logical next step is to try to find out “okay, well then what is to be done?”

But you have to give a background lesson first if the book/site of it you send them doesn’t explain in the preface, the whole thing that in the context of her book “Social-democrat” meant socialists in general; both revolutionary and the Bernstien-type ‘voting in socialism through reform’ revisonists; because this was in like 1900, before the failure of the second international and resultant split of the communists. It’s only after all of that and the 3rd international and the betrayal of Rosa and the communist KPD by the reformists that that the “social democrats” came to be understood as we know them today, reformist welfare liberals (which, incidentally, thoroughly and undeniably vindicates Luxemburg, Lenin and the Bolsheviks, et al and their criticisms of reformism).
