Yes, “Stalinist” is actually more accurate. I would agree completely!
I use it in a literary context and refuse to call it “Orwellian” since he was writing about the horrifying behavior of Socialist in the West who were absolutely unwilling to concede any wrong on his part.
Orwell wasn’t to blame for the actions any more than it is wrong to call “it” Borking when dead Red Ted Kennedy was behind the tactic.
