If he says moderate, ask him what sort of positions would it take someone on the Left to be described as an extremist.
Yea...right?
or bait him. Ya know, Stalin really did attempt to create a better society. In fact, if given a lil more time, he might have just created the perfect scenario for societal harmony.
If he say’z to ya, “young man, your correct. Stalin was truly a revolutionary and a people’s leader”.
Ya then know how radical his innerds are.
