Further to my post at https://gnwmythr.blogspot.com/2022/08/post-no-2270-heteronormativity-test.html, most of the depictions of light vs. dark - especially in Star Wars - are wrong: it is actually sanity / maturity / wellbeing vs. insanity / immaturity / illness - which makes the absurdity of the "balance" between light and dark even more clearly a load of rot.
In fact, the behaviour of characters in the Star Wars movies makes that quite obvious, when one has the correct perspective.
