Friends dragged me to Inside Out 2 and it was saccharine dogshit that mostly made me think of my awkward moments in high school sports. To its credit it was only 90 minutes long. Anyway Zizek's idea would have been much more unhinged and interesting.
Overall it’s a fine inoffensive kid’s movie with a basic, at worst harmless message about not letting your fears get the best of you and staying true to yourself while also accepting change/growing. Your one example is a very very small part of the movie, and at that the most political/divisive thing in it.
