I feel like talking about Stalin is like walking on eggshells... You don't want to go, "Stalin's death toll is overexaggerated, in my opinion he didn't kill enough people!!!" because that will make the average person instantly stop hearing you
What's the best way to talk about Stalin in a sensitive way that doesn't trigger a fight or flight response?
You could also read what I directly linked you earlier and evidently didn't read a word of it. But yeah, if I googled "anti-communism", I'm sure I could find plenty of sources alleging a lot of terrible things about it, like ones written by the western empire and by fascists and their intelligentsia. It's almost like in power struggle, if you don't defeat the exploiting classes, they will slander and fight you instead of just giving in to a better world. Did you know the USSR was invaded by western powers very early in its life? Far before it had time to do most of the atrocities that anti-communists claimed it did. Meanwhile, Nazi Germany was largely left alone by some of those same powers until late in WWII (or even had connections between). Why do you think that is, hmm?
