I think equally important as teaching these things to begin with is letting students know when they're being taught a simplified model, and that serious academic discourse of the subject is still evolving and/or involves much more nuance (which is pretty much always). some people who do pay attention in science classes nonetheless think that what they learned is gospel and never re-examine it, or stubbornly refuse to acknowledge when said nuance is relevant because it seems to contradict the simplified model they've cemented in their brain as the whole truth. the kind of people who say things like "I know there's two genders because I learned it in high school biology" and apparently never considered why there would be collegiate and post-graduate studies on biology and gender (or why those are two entirely different fields of study) if we all already learned everything there is to know in high school.
