You can absolutely present a complicated topic to someone who isn’t educated in that field, or even has low education at all, if you are being humble about how you explain it and try to meet them at eye-level.

I vehemently disagree. Some people (maybe most people) are too stupid to understand nuance. They need to be told what to think.

Perhaps this is just a failing of our educational system and not a fact of human psychology, but it’s still the condition of the world today.
