i’ll freely admit i’m not reading books on the subject

Let me first clarify a few points then.

Marx and Lenin were also "authoritarian." You should read Engles' On Authority, it's not long and explains his position on the matter, which was consistent with Marx.

"Stalinism" isn't really a thing, nobody calls themselves that, it's just a pejorative for Marxism-Leninism, which was Stalin's stated ideology (in fact, he's the person who coined the term). Marxism-Leninism ("Stalinism") is the most prevalent ideology among self-described communists globally, particularly in the global south.

If Sanders just wanted an authoritarian figure to compare Trump to, there are no shortage of right-wing ones who have much more in common with him. The choice of Stalin seems to be intentional, to distance himself and his own brand of socialism from Stalin and other M-Ls.

I believe this is a flawed strategy, in the same way it would be to accuse a witch-hunter of being a witch. The problem is that you're accepting the premise that witches are real and need to be hunted, and at that point it becomes a question of who can better make the case that they're not a witch - which is going to be the witch-hunter, because that's their job, they know how to play the game, they made the rules. In the same way, right wingers are always going to be more convincing anti-communists than someone who calls himself a socialist, they made the rules of the red scare and they know how to play it. The real way to defeat the witch hunt is to have enough people who aren't afraid of being called witches, and the way to defeat red scare stuff is not to accept the framing and punch left, but to say, "So what if I am a Red?"
