I think the answer is "probably". I think he is probably not feigning. I think he probably has no clue of what goes down at the Finland Station.
At the Finland Station, you see, elections are fine only as long as they produce socialist results. When push comes to shove, it is indeed the case at the Finland Station that, as Lenin wrote: "Every direct or indirect attempt to consider the question of the [election] from a formal, legal point of view, within the framework of ordinary bourgeois democracy and disregarding the class struggle and civil war, would be a betrayal..." Sunkar can see this not as the act of "crazed demons", and instead choose—and it is a choice—to see Lenin and company as "well-intentioned people trying to build a better world out of a crisis". But on-the-ground really-existing "ordinary bourgeois democracy" is and always has been of little value to Lenin's flavor of socialists.
